My Sql Express Is So Slow?
Aug 25, 2006
Has anyone else noticed delays with SQL Express? I'm not really talking about delays on the queries but just delays in general response. For example: everything is running great, then for about 2 minutes I get connection timeouts etc can't even open stuff in the management studio without getting timeouts ... then as strangely as it started everything goes back to normal and requests are served again.
The server has nothing on except 1 website, its Win 2003 Server. 512MB Ram on a PIV. The memory usage is low and during the "lockups" the machine isn't showing any processor usage and SQL mem usage is around 40Megs.
I am not using User Instances either. Nothing in the event logs. What is odd, is its happening on 3 of my machines ..... all with different sites, the only thing in common between them is SQL.
thanks,

Some queries take a long time to complete.
Setup is:
- SQL Express SP2
- Windows Vista Business
- 2 GB RAM
- Core 2 Duo processor
- Connecting to (local) server with SQL Authentication
- only 1 Instance of MSSQLSERVER
Simple queries (SELECT * FROM TableName) wher the table has only a few records. This query may take up to 30 or more to execute. This slowness is consistent to certain tables. Other much larger tables run queries fine.
If a different computer logs in to the same server, queries provide instantaneous results.

I posted this in one of the VB forums but I'm starting to think itmight be more appropriate to have it here, since it really seems to bea SQL server (MSDE/Express 2005) problem:Hey, all, I have a problem with queries against a SQL server instancethat I just found and is causing me fits. I hope someone can pointmein the right direction, please. TIA.Basically, I got a Vista OS machine to test my VB6 app on it as someof my clients will be switching over in the coming months. I went toa local Circuit City during early business hours in the middle of theweek and I installed my application on each of 5 PC's on the newVistaOS (Tuesday, when it was released). I had read that MSDE 2000, whichI normally use as my DB is not supported on Vista so I had downloadedand was using SQL Express 2005. Each system had at least a 1.9 GHzdual core processor and 1 GB of RAM. One process in my program findsrecords in one table that do not match records in another table andthen reports those un-matched entries. On my development machine(laptop with 1 GB of RAM, XP Pro SP2, MSDE 2000 (current SP), 2 GHzCentrino (IIRC)) the process takes less than 30 seconds consistently.On each of those 5 systems at Circuit City the process took 5 minutes(on each of 3 HP machines, a1700n, a1720n, a1730n, and 11 minutes oneach of two Gateway systems (the model numbers of which I forget atthe moment). Each of these computers should be much faster than mylaptop, and some had twice the RAM, and all had SATA or SATA IIdrivesinstead of my piddly 5400 laptop drive, I would have thought they'dall be faster but were abysmally slow.So, seeing a huge difference in the time, and to try to keep thisshort and sweet, I fired up another computer I have, running XP SP2,on 512 MB RAM, AMD Athlon 2300+. First I loaded MSDE 2000 and myapplication and ran the process. < 30 seconds on each of multipleruns. Second, I unloaded MSDE 2000 and installed SQL Express 2005andmoved the DB to it (sp_attach_db) which caused some upgrading(messages reported in OSQL about update/upgrade). When it was done Irebooted, to be sure, and the ran the program and the process again.On the same data, on the same computer, the process took 7-9 minutesconsistently on each of several runs. This makes this part of theapplication unusable, and even the simple stuff like grabbing asinglerecord from the DB (maybe 5 columns of no more than 500 bytes total)is noticeably slower on the SQL Express 2005 than on MSDE 2000.So, the problem seems to be with my interaction with the DB. I amusing ADO 2.8 in VB 6 (SP 6). I use DSN-less connections with aconnection string like: Driver={SQL Server};server=(local)caredata;database=caredata;Uid=sa; Pwd=<password>I use the RecordsSet Object to open the data similar to this:oRS.OpenstrSQL$, oCN, adOpenKeysetafter the oCN object has had the connection string set and the objectis opened.Considering that the same computer, against the same data, with thesame program, takes about 14 times (or more) longer to run, then ithas to be either that SQL Express 2005 is slow OR that my program isinteracting with it in an incorrect manner.Can someone point me in the right direction, please?Thank you.--HCSo, the problem isn't Vista

I've just moved a website/database application from windows server 2000 and sql server 2000 to windows server 2003 sp2 and SQL 2005 Express SP2. Database intensive pages now take about 40 seconds where before they took 2-3 seconds.
Things I've tried that haven't helped...
- I changed the ADODB connection string
from: sCnString = "dsn=mydsn;Database=mydatabase;uid=myuid;pwd=mypassword"
to: sCnString = "driver={SQL Native Client};server=myserverSQLEXPRESS;Database=mydatabase;uid=myuid;pwd=mypassword"
- Checked that autoclose is false.
What else can I look at?

Hi,
I have got an application running which connects 2 databases and performs an action that copies data from one database to the other database.
When using SQL Server 2000 MSDE, it takes about 5 seconds.
When using SQL Server 2005 Express Edition it takes about 30 seconds.
For testing 2005, I use 'upgraded' databases, so same indexes and data. I tried reindexing the databases, but always get the same result.
My setup string for installing SQL Server 2005 Express is :
/qb ADDLOCAL=ALL INSTANCENAME=DBNAME SECURITYMODE=SQL SAPWD=QWERTY SQLACCOUNT="NT AUTHORITYSYSTEM"
The code (ADO) is something like :
SELECT FROM original database
-- do something with data
INSERT INTO other database
Until EOF
Any idea how to solve this ???
P.S. When perfoming a simple Query on the databases (with 1.000.000 rows result) with SQL Server Management Studio Express, I see 37 seconds for SQL Server 2000 and 33 Second for SQL Server 2005. That is more the result I expect.

Hi,
I use a Remote Sql Server Express instance, and I have a strange behavior.. The first connection is really slow and I don't know how to fix that.I read some posts about this topic but I didn't find the right solution.Is there a way to "keep alive" the connection between my IIS server and the SQL one ?I check the auto-close property and it sets to false.
Any help ?

Hi,
I've recently installed SQL Server 2005 Express on my PC (winXP).
I'm finding that SQL Server Management Studio Express runs very slow. Every simple task takes 10-60seconds (open table, creating a table, saving anything etc). I can't find an answer to this anywhere. I've read neumerous articles that people wern't online therefore it was running slow because a certificate was trying to verify in the background... but I'm online and I've disabled the certificate so it can't be that.
This is a fresh install so I can't understand why it runs so slowly! When I used to use enterprise manager with SQL Server 2000 it worked at lighting speed.
What's going on?

Sql 2005 Express with XPP SP2 and the latest MS updates sometimes runs very slow.
A SELECT which should take a fraction of a second can take several 10s of seconds.
I have checked autoclose is OFF for database using
use master
go
exec sp_dboption 'your_db_name','autoclose'
And it is definitely showing as OFF
I've looked at the Activity Monitor and when stalled it shows one or two processes for my database which are sleeping with 1 or 2 open transactions. When I look at their details they are simple select statements.
Often when my computer should be idle SqlServer.exe can be consuming 20 - 30% of cpu
I've noticed that I have TWO sqlservr.exe showing in my Task Manager, Processes display
One sqlservr.exe is 27K using about 17% even tho computer is idle has username NETWORK SERVICE
Other sqlservr.exe is 343K using 0% has user name SYSTEM
I don't know why.

I am running simple queries against test SQL Express installation and they take a very long time to return data. I have two SQL Express instances installed on colleagues' machines to which I connect for my testing and both exhibit the same problem. The setup is Windows XP SP 2 with 2 GB RAM and 3.6 GHz CPU. I am querying a table with around 7000 records and my query is simply SELECT TOP 1000 * FROM MyTable. It takes over 10 seconds to return the recordset!
I have done the research and found posts, which talk about AUTO_CLOSE option, indexes, query execution plan, etc. I have done everything those posts recommend, but performance is still terrible. All the instances have SQL 2005 SP2 applied.
I also found that the query runs fast locally on each SQL Express instance, the problem seem to happen when I am trying to pull the data over the network.
I am really not sure what else to look for.
Thank you,
Michael

I have a 2GHZ cpu with 1GB of RAM. I occassionally see very slow (long) queries against a local SQL Server 2005 Express (SP2) database. The issue occurs against different SQL Queries, but all queries are rather basic select statements Perfmon shows that the SQL Server counter for the "MEMORY GRANT QUEUE WAIT Avg MS" gets extremely high (25000+ ms). Perfmon also also shows that PAGING is not occuring, and the system is not under unsual stress. The problem is not reproducible with MSDE.
Has anyone seen this issue, or have any recommendations for a next course of action?

I am writing a data access web page, but I find that the excution speed is too slow.
My data base is just a data table which have five columns: id, code, quantity, price and Date. The data base has about 45000 rows. When I use OSQL or Query function, speed is just fine.
Here is the main code which I think cause the speed slow:
string conn = ConfigurationSettings.AppSettings["connectionstring"];
SqlDataAdapter adapter_2 = new SqlDataAdapter("select * from table",conn);
DataSet ds = new DataSet();
adapter_2.Fill (ds,"table");
DataTable YahooOrders = ds.Tables["YahooOrders"];
DataRow[] product = new DataRow[20000];
.......
foreach (string s in split) // actually the split here has only one string in it
{
product = table.Select ("code like '"+s+"%' and Date >='"+minDate+"' and Date <='"+table.Select("Date = Max(Date)")[0][1].ToString()+"'");
foreach(DataRow myRow in product)
{
int count = Convert.ToInt32(myRow[2]);
itemQuantity = count + itemQuantity;
revenue = Convert.ToDouble(myRow[3]) * count + revenue;
// get product code, ignore repeated code
int myIndex=code.BinarySearch( myRow[1] );
if ( myIndex < 0 )
code.Add(myRow[1]);
}
orderQuantity = product.Length + orderQuantity;
}
The first foreach actually excutes just one time, so it won' t cause any speed problem.
The second foreach' s job is to sum each column of specified rows which is product here.
So, any ideas about this?
Thanks!

All,
Actually from the application the developers are using count(column) to know the no. of rows resulted by a statement which joins many tables but its taking lot of time.
Is there an easy way to get the count of records(result set) of the output.
I cant use sysindexes b'z i need the count of the output genereted by the SQl Statement which joins many tables and retrieves many rows.
Thanks,
Sajai

Hi fellas (and girllas),
Got a problem (duh!). My MSSQL Server lags. Now, mind, it doesn't lag all the time. And it seems to be independent of the # of users trying to access the server. And it random clears itself up. And the problem doesn't present itself in SQL MGR, just on the web app we're running on it.
Setup:
SQL Server 2k running on 2k3 w/ IIS & backup exec.
All SQL data files are on a raid5 SCSI U160.
App:
Intranet App developed by us for us. ASP.NET & VB.NET.
Symptoms:
When queried server takes a LONG time to respond. So long infact it has become counter productive. When taking a look at the server, the CPU usage hovers between 50-75% and spikes up to 90% every now and then just for kicks. The memory usage is 2.35gb out of 4gb. To fix this we have to kill and restart all the SQL services.
Any thoughts on what to look at? There're indexes on the required FKs and the heavily queried columns. We're at a loss here.
Thanks for any helpful help!
=Me!

A vendor's application is performing slow. Vendor tested it in QA and it's slow. End-users run it in PRD and it's slow. The application calls SP1, and SP1 calls SP2. Inside SP1 has a cursor. I believe as the db gets larger. The application is going to be even slower. What can I suggest to the vendor in order to fix it? Tell them to re-write the application code? Eliminate cursor?

Hello,Were using the data transfermation service to copy in an Ingres II 2.5database to an SQL Server 2000 database. Small databases don't present anissue, but when pulling one across that's about 20GB its been taking between12 and 24 hours. Both systems are relitively quick boxes and neither of themare tapped out on processor, disk I/O or network resources.I do have the "Boost SQL Server priority on Windows" checked under it'sproperties and all the processors are checked to be used.Does anyone know if there's a way to tweak SQL Server or Ingres to handlethis a little quicker? Or even an idea where the bottleneck could be may behelpful.Thanks,John.

I've got a performance question about a clr tvf that I have created. When I query the function it takes about 30 seconds for it to execute as apposed to < 6 seconds when I execute the same code in a console app (the 6 seconds includes outputting the returned data to the console, without writing the output to console it executes in about 1 second). Both the function and the app are iterating (>40,000) and returning ( >10,000) the same number of rows. I've noticed the following when viewing the executions in the PerfMon:
* the sqlclr tfv kicks the % Processor Time up to 30 for 30 seconds, the console app has % Processor Time at 9 for about 2 seconds
* .NET CLR Memory - Allocated Bytes/sec spikes anywhere from 1 to 3 times during the sqlclr query at about 44MB/sec. It barely registers if at all when the console app runs.
* In either case, % Time in GC is at zero.
I'm assuming that there are some configurations I'm ignorant of that can help me tune the execution. I can't imagine that it takes SqlServer that long just to iterate through the records.

I have recently decided to make the change from Microsoft access to SQL Server believing that it's a bigger faster beast with better parameterized queries and triggers and all that. BUT.I have some client data that I imported from their original paradox files.The invoice lineitem file contains over 1 milliion records.When I open this table in access and click show last record, the record is displayed in about 1 or 2 seconds.I used the upsize to SQL Server tool in Access to shift my data into SQL Server.When I use the Express Mangagement tool to open the same table and say show me the last record, it takes 17 minutes.I admit that most numeric data types have been translated to floats, so that's probably not good.But I cant alter them from floats to numeric or decimals using the table design tool.Do the conversion anomalies make up the whole reason why SQL Server seems so incredibly SLOW! ?????????

I am running the following BCP to extract a table with 156641604 rows.
bcp TestDB..data out test3.bcp -T -b1000000 -a32000
When running this i notice that the disk read bytessec counter in performance monitor on the drive that has the database devices is only reading 30mbsec. I am writing the bcp file to a different drive. Both drives are far more capable of achieving much higher IO. Is this a limitation with BCP or are there futher switches available that would speed this process up. Also the drives are both local so the bottle neck is not network. Any ideas?

This sounds like a pretty easy one. I have a SQL 2000 database with 2-3.4GHZ CPUs and 1GB of RAM. I have one database on it. I go in Query Analyzer on another machine and run a simple query like 'SELECT * FROM USERS' which should return 15,000 rows.
IT takes 30 (thirty) seconds to finish this query. OMG
Where do I start to decipher why on Earth this takes more than .01 seconds?

Hello,
We have Sql Server installed on the Windows 2000 machine.
There are 2 databases that the employees access on it.
When the machine is just started, there are no problems but after some time the connections get really really slow and then eventually become impossible to connect. We did not have this problem before until we had a computer crash and then Sql server was installed on a new machine. The problems started here. We had 64mb of ram and we put in another 64mb thinking this would solve it but it did not.
On the task manager the cpu percentage stays constant at 100% and the virtual memory increases and increases very slowly until it has reached it's maximum (which is 600mb).
Any information would be greatly appreciated.
Thanks very much,
Kostas

I have a dts job set up to transfer 550,000 records from a dbf file into a sql server. If I just let it run, there is a 9-10 minute delay, then it starts. If I try to schedule a job, it fails completely. I looked up ways to get it to execute quicker, mainly going to the advanced tab of the transform arrow and making the inserts 1000 at a time, the table locked, turning constraints off. Any advice on how to speed it up or why the job is failing?
