How To Increase SSIS Performance
Nov 3, 2006
Hello again,
I'll just throw my question: how could I increase SSIS-performance?
I have a really heavy job with thousands of records my base selection, then I perform some lookups (I replaced most of them by sql) and derived columns (again, I replaced as much as possible by sql). Finally, after a slowly changing dimension task, I do update/insert on a given table. Is there a trick to speed up lookups and inserts (something like manipulating the buffer sizes - just asking).
Fact is that I replaced a script task by pure sql-joins and gained 6 of the 12 hours this job took.
Any ideas?
Greets,
Tom

Hi,
I created a view on two huge tables. I tried to run a simple SELECT statement on this view and it took me several hours to obtain the result. How can I improve the performance of a view? The view should make use of the indexes built in both table, am I right? Thanks.

"Cursor provide row-by-row level processing and it will store the result sets in 'TEMPDB' database".
(Because of this) or (By using Cursor in Triggers or Stored Procedures) the performance will increase or performance will come down?. I am thankful if I get a good reason for this?

Hi,
I am writing an ASP based application that creates a dynamic querry and then
executes it and displays results. I was thinking about writing a stored procedure to increase performance. How much can the SP help me boost querry responce time ???
Thanks for your time,

Hi,
Can any one give me an idea how can i increase performance of the stored procedure.
In SP many temporary tables are used.
Also i need a information from any one you that is there any tool to find out the performance of a query or SP etc.
Thanks

Solutions are easy. Understanding the problem, now, that's the hard part

Hello,
I have 3 tables (A, B, C) with milions of records (A ca 5 milions, B and C ca 10 milions).
I have created a join betwenn them
select some fields (A, B, C)
FROM
A as a
JOIN
B as B
on
a.a1 = b.a1
and
a.a2 = b.a2
JOIN
C as c
ON
b.b1 = c.b1
and
b.b2 = c.b2
Where fieldtime <= date/time
But it takes to much time: aftre 2 hours and half is still running.
Do you know how to increase the performance?
Thank

Dear all,
I'm using SQL Server 2005 Standard Edetion.
I have the following stored procedure that is executed against two tables (RecrodedCalls) and (RecordedCallsTags)
The table RecordedCalls has more than 10000000 Records and RecordedCallsTags is about 7500000 Records
Now the lines marked in baby blue are dynamic (Dynamic where statement) that varies every time this stored procedure is executed, may it contains 7 columns in condetion statement or may it contains 10 columns, or 2 coulmns.....etc
Now I want to create non-clustered indexes on the columns used in the where statement, THE DTA suggests different indexing whenever the where statement changes.
So what is the right way to created indexes, to create one index on all the columns once, or to create separate indexes on each columns, sometimes the DTA suggests 5 columns together at one if I€™m using 5 conditions, I can€™t accumulate all the possible indexes hence the where statement always vary from situation to situation, below the SP:
CREATE TABLE #tempLookups (ID int identity(0,1),Code NVARCHAR(100),NameE NVARCHAR(500),NameA NVARCHAR(500))
CREATE TABLE #tempTable (ID int identity(0,1),TypesCount INT,CallsType NVARCHAR(50))
INSERT INTO #tempLookups SELECT Code, NameE, NameA FROM lookups WHERE [Type] = 'CALLTYPES' ORDER BY Ordering ASC
INSERT INTO #tempTable SELECT COUNT(DISTINCT(RecordedCalls.ID)) As TypesCount,RecordedCalls.CallType as CallsType
FROM RecordedCalls LEFT OUTER JOIN RecordedCallsTags ON RecordedCalls.ID = RecordedCallsTags.CallID
WHERE RecordedCalls.ID <= '9369907'
AND (RecordedCalls.CallDate BETWEEN cast ('01 Jan 1910 00:00:00:000' as datetime ) AND cast ( '01 Jan 2210 00:00:00:000' as datetime ))
AND (RecordedCalls.Duration BETWEEN 0 AND 1000000)
AND RecordedCalls.ChannelID NOT IN('62061','62062','62063','62064','64110','64111','64112','64113','64114','69860','69861','69862','69863','69866','69867','69868')
AND RecordedCalls.ServerID NOT IN('2')
AND RecordedCalls.AgentID NOT IN('1000010000')
AND (RecordedCallsTags.TagID is null OR RecordedCallsTags.TagID NOT IN('100','200'))
AND RecordedCalls.IsDeleted='false'
GROUP BY RecordedCalls.CallType
SELECT IsNull(#tempTable.TypesCount, 0) AS TypesCount, CASE('English')
WHEN 'Arabic' THEN #tempLookups.NameA
ELSE #tempLookups.NameE
END AS CallsType FROM
#tempTable RIGHT OUTER JOIN #tempLookups ON #tempTable.CallsType = #tempLookups.Code
DROP TABLE #tempLookups
DROP TABLE #tempTable
Thanks all,
Tayseer

Hi All,
Our client is a multinational Cigar company and we have been building SSIS packages for them for extraction of data into data marts.
We tried to do all the tasks using T-SQL procedures also and tried comparing the performance of procedures and SSIS packages.
We found out that procedures are better than SSIS packages in performance(Time taken). Why is this so?
We expected the SSIS packages to be much quicker but it was not the case...
Thanks,
Prakash.P

I have been working on a project last few months. I have developed the project on my laptop, which is resonably powerful. It runs through fine within 9 mins with sample data set.
If I replicate the same environment on a 64 Bit machine with 32 Bit Win 2003 and SP1, it takes just over 7 mins.
If I rerun it on a 64 Bit machine with 64 Bit Win 2003, it takes between 21 and 24 mins.
We are executing the packages via dtexec on a command prompt.
Has anyone seen same behaviour?
Thanks

I am currently in the process of migrating DTS packages to SSIS. I am finding that most of the packages are running faster, but some of them are taking longer to execute.
The DTS package copies data from our Production server to Development. It uses a Copy SQL Server Objects Task to copy only the data from about 50 tables. This takes about 3.5 minutes. I created the exact same package in SSIS using the Transfer SQL Server Objects Task and it is running about 5 minutes.
Another package I am having this problem with is only copying data from 1 table using a Copy SQL Server Objects Task. This package executes in 19 minutes. I have created the exact same package twice. Once using Transfer SQL Server Objects and once with a data flow task. The Transfer SQL Server Objects package takes about 50 minutes while the Data Flow package takes about 40 minutes.
As I said most of the packages are faster with SSIS so this is why I am confused on these couple where they are just copying the data.
Any help is much appreciated.
Thanks,
Sam

Hi:
I've written new SSIS packages to do what DTS packages did and the
performance I'd say is about 20 times slower. In this package, I have
a loop that loops through different servers based on server entries in
a SQL database. Each loop pumps 10 tables. The source query is set by
a variable and the destination table is set also by a variable, since
all this data goes to the same tables on the SQL server and the
definitions are all the same on the source server (Sybase). It's still going and has taken about 12 hours to pull roughly 5 million records.
The source query ends up being:
SELECT *, 'ServerName' FROM SourceTable1 WHERE Date >= Date
The 'ServerName' , the "sourcetable1" and the "Date" are all set by
variables which in turn build the source query variable.
Anyway, I just mention this for completeness--I would think setting
the variables which have anything to do with the pump's performance. How can I check
to see where the performance is getting held up?
Also, I have checked via ping the timeout to the 3 servers. The slowest one pings in about 62 ms, the fastest at 1 ms, and the other somewhere in between.

Hi,
I have 4 execute packages say A, B, C, D. These packges contains packages for data transfer in turn.
Package A - 15 packages
Package B - 15 packages
Package C - 20 packages
Package D - 20 packages
When i run these packages one at a time in the order A, B, C, D then the execution time is around 17 mins.
If I make a parent package and put A, B, C, D in sequence in it, executing this parent package increases the execution time to arnd 50 mins.
Pacakge A, B, C, D doesnot run in parallel. They run one at a time. So i was wondering why the there is so much time difference.
Please let me know if theres some configuration settings to make the parent package efficient.
All the test conditions are same in both the cases. The source and the target are SQL server which are on the same machine as the SSIS.
Thanks,
Vipul

I have a bunch of packages that take views and create tables from them. Some of the views are rather complex, but the packages themselves are very simple... drop and re-create a table using the data from a view on the same server. We create a new DB for each year, and this year we've upgraded to a new server with SQL 2005, so our DTS packages on the 2000 SQL server had to be recreated in SSIS on the new server. No problem, as I said the packages are really simple. But when I create the packages in SSIS they now take an extremely long time to execute, and I cannot figure out why.
For instance, one DTS package would take approximately 5 minutes to run when the view contained hundreds of thousands of rows and the underlying tables contained millions. But now, even with MUCH smaller tables (since it's the beginning of the year, new DB) the SSIS package I created on the new server takes over an hour, literally. The view that the SSIS package is using to create the table only takes about 15 seconds to execute in management studio (only about 16,000 rows). How can this possibly take so long??
the new server is virtually the same hardware-wise... 4 x 2400mhz, 4gb ram, win2k3 server

Hi,
our package have design like this,
OLEDBSource à Derived Column à Lookup

Matching Records Un Matched Records
| |
OLEDBCommand OLEDBDestination
(Update) (Insert)
and our source & destination table are oracle. when we execute the package the performance is very low and some times its showing like processing ( yellow color) even for 1 hrs .what could be the problem.can any one help us.is there any reason like when we use orcale database this will slow down the performance of package

I created a dataflow that transferred about 1 million records from a SQL database on one server to a differend SQL database on the same server. The processing took about 30 minutes. I used the Fast Load option.
I then created a "Execute SQL Task" and wrote a "SELECT * INTO TABLE" and this processing took about 30 - 60 seconds.
Can someone tell me why creating a Data Flow Tak would take so much longer or give differences between the two options above? Can someone give some pointers on how to make a Data Flow task more efficient?
Thanks.

Hello Everyone,
Can any one update me up performance turning of SSIS and what difference would it make if I change the default value of this two parameter in each Data Flow.
DefaultBuffermaxRows
DefaultBufferSize
Also update me on what is these parameters used for.
Thank you

I have a multi-threaded C# application that loads a bunch of tables into ado.net datasets in memory for surrogate key lookups. Depending on what else is going on, it can process 100,000 to 170,000 rows per minute and usually utilizes 20-30% of each cpu.

Hi,
I created procedure which completes execution in 20 mins in sql server 2005 but if i kept the same procedure in Execute SQL Task in SSIS and executing means, it is taking 3 hrs.
Is there any way to increase the performance for the above same.
Any help would be appreciated

On 32 bit SSIS installations, both of the following performance counter objects are visible in perfmon.
SQLServer:SSIS Service
SQLServer:SSIS Pipeline
On 64 bit SSIS installations, only the following is available.
SQLServer:SSIS Service
The SQlServer:SSIS Pipeline counters are nowhere to be found.
Should I re-install? Is this a known issue with 64 bit SSIS?
P.S. Remote or local access administrative access with perfmon makes no difference, the "SQLServer:SSIS Pipeline" performance counters don't appear in the listbox when connecting to Windows 2003 x64 server.

Hello,
I have been running massive ssis packages and testing the performance.
This is my execution design:
I have a main package that gets a list of packages to execute from a table.
Then using a foreach loop in send the package to execute ( somewhere in the middle i delete the corresponding old log file for that package ), each of the packages configures themselves from the parent package variables.
What i have been analysing tells me that for example a package runs in 2 minutes and then the time wasted from the end of the package to the start of the other task is in average 3 to 6 minutes... thats alot... since i run about 20x12 packages witch gives me of wasted time about 20 hours.
My question is... what can be causing the delay between the end of package and the start of the other one...
The tasks types i am using in the execution controller package are:
Foreach loops, For Loop, File System task, Execute Package Task and some Execute SQL Tasks
Best Regards,
Luis Simões

We have SSIS installed and everything is working great. We are now to the point of wanting to tune one of our longer running packages and the Performance counters are not working. At all. They show up ok but the counter is always at 0. Is there anything special I have to do to get this to work.
One comment I fould was that the Performance Logs and Alerts service needs to be running to see these counters. I tried to start it and it immediately quit. I set it to automatic startup up and run a package. The counter still read 0.
Is there anything else out there I can try to get these counters to return somthing. Thanks.

My apologies if this is a very basic question, but I am having a very difficult time finding the answer.
My very, very simple dataflow task is PAINSTAKINGLY slow. (It took over an hour to transwer @300,000 records). I'm doing no transformations whatsoever. In fact, the only reason I'm using the Data Flow component here is for its error tracking capabilities.
Here's a brief description-
1) The source is an OleDB datasource object that uses an OLEDB connection to access a SQL Server 2000 database.
2) The output from the source is dumped directly (no data transformations) into an OLEDB Destination Object (uses an OLEDB connection to access a View on a SQL Server 2005 database). Individual row errors are pushed to a seperate logging table.
Based on the advice of an article I read, I removed the "OleDB Destination" object and used the records from the OLEDB source as the input to a RowCount Transformation. This still took a SIGNIFICANT amount of time. I'm guessing that my problem is with using an OleDB Source component???? That seems really strange though... wouldn't it be optimized? What are my workaround options?
Any help is _much_ appreciated.
Thanks,
Jess

Hi,
I have multiple data flow tasks defined in my package. The task of the package is to extract data from Oracle/InfoLease tables and put them on to a SQL Server 2005 database.
Listed below are few queries that I had:
1. In SSIS package, I need to add "Data Conversion" component to convert from Unicode string datatype to String datatype. This was not required in SQL Server 2000 DTS package.
2. By default, Individual transformation is created for each column. Is there a way, to create one transformation for all columns.
3. This SSIS package is being executed as part of a job. The execution time takes around 33 mins.
The same functionality of the SSIS package was replicated in form of SQL Server 2000- DTS package and was executed in form of a job. This execution got completed in 9 mins.
So there has been a drastic increase in job execution time. Are there any ways to increase performance.
Any help will be highly appreciated.
Thanks.

Hi -
I am facing 2 problems :
PROBLEM 1 :
We have a few packages that run pretty fast on a desktop server with 2 Gig RAM, Dual processor (approx 4-5 hours). But the same packages run very very slow on the another server containing 8 CPU and 12 Gig RAM (ran for 24 hours without completing).
PROBLEM 2 :
The CPU% ranges from 40-80% and the PF usage is stagnant at 2GB on desktop server for the same package. But in the 8CPU server, the CPU % ranges from 0-10% but the PF Usage raises from 750 MB to 8 GB.
This has become critical to our application.
TIA,
Shabs

Hi,
I would like to know if any one out there has the same performance issue with ssis packages once you move from a 2GB of RAM, 4 processors to a 16 GB of RAM with 8 processors. My SSIS packages performance is extreemly slow especially for one of my loading packages. The execution time for that package is almost double as compare to the execution time on the smaller box (2GB, 4 processor). There is no transformation for this package. It is just one lookup for existing or not and then do the insertion. This package is handling insertion of millions of rows.
The 2GB of RAM, 4 processor box is 32 bit with SP1 and the 16GB of RAM, 8 processors is 64 bit with SP2. However, I did try to force the execution of the package in 32 bit on the 64 bit server. The execution time is still the same as it is executed in 64 bit mode.
If any one out there has experienced the same thing and has known the cause to the problem, please let me know I would greatly appreciated.
Thanks,
MN
