Performance Issue With RDS Using IIS6
Two Windows boxes with identical COM objects and databases for comparing and
testing purposes (2000 and 2003) exists as virtual mashines on one big host
server. Network settings for
these VMs are identical (except IP address, of course).
We have on remote client request executing time (getting 3000 rows from DB ~
1.4 Mb amount - measured via Network Monitor) about 3 sec on Windows 2000 VM
and 50 (!) sec for 2003 VM. For local request both time are identical and ~
1.5 sec. Code:

I'm using MSXML2.ServerXMLHTTP to retrieve a webpage. It works, but is unacceptably slow (~20s) when retrieving remote webpages (anything outside our network).Is there any way to improve the performance?

im trying to build some custom shopping cart for a client
what i know about shopping carts is the main idea which is an array stored in the the client's session
also i know that this point (the session) may cause some bad performance and here is my point
any cart contains just the product id and number of items or something like that (some people says data dictionary is good here)
the cart im going to build contains alot od data coz the site client when choose to add some item to his cart must be redirected to some page with a form to add many details about his needs with the product so the session here will carry alot of data ........
so i thought in 2 iedeas
1- array into session
2- some databse table carries all of temporary data with a unique primary key for every session but i need to know the best selution for the best performance

If I a loop that displays a list of records on a page, lets say a list of contacts (lets say 200). The question that I have is does it effect the performance if I add inside the loop the following:
if Arr[0,index]="1" then
.....
end if

I have a list box with about 500 users in it. I have to populate that on a site. It causes extreme slowness. I am using classic ASP with MS SQL. What is happening is the users are stored as a number (a user_id) and that number is looked up. Then that number is passed through a simple function to turn the number into a name. The names are stored in the DB in first_name, last_name format. The company wants the list box in first_name last_name format so the function is needed. Should I look into database caching, caching the list box somehow, making another table of the user_id's and names in the correct form, or some other option. Once again, I am not using ASP.NET, but classic ASP instead.

I am running the WebService / CurrentConnections performance counter.
It works fine for one site I'm looking at, but not for another.
The one it doesn't work for, the polling vertical red line doesn't even
move.
Is there a setting somewhere that controls whether a web site can be be
'polled' or not?
I am using Windows Server 2003 Standard Edition.

I'm maintaining an ASP Classic file that has HTML withing
Response.Write methods such as
<%
Response.Write "<table><tr><td>"
Response.Write testVariable
Response.Write "</td></tr></table>"
%>
Would their be a performance hit if I were to write this instead?
<table><tr><td><%=testVariable%></td></tr></table>
I need some confirmation.

I have a database with 300,000 records. I have two "DATE" columns and
I need to calcluate the difference and display the number of days in
one of the reports. I was wondering if this calculation of days should
be done on the fly or is it OK to have a "Difference Date"
column[Contains Number of Days] and retrieve the same
Their will be not more than 50 concurrent users accesing it. However,
in the next 6 months the record size is expected to reach 800,000. The
database will be hosted on a shared hosting on the internet

any 1 know of any resource that provides Active Server Page performance on differenct server platforms. I am interested to know what the page/sec, concurrent users (on avarage, this of course depends on other factors) is for Dell PowerEdge servers.
I recall that 40page/sec on 800Mhz server a few years ago was really good. What can I expect from a dual PE1750 3GHz Xeon?

I have an asp site that of late is having a very very slow response at the production environment and it is taking 6-7 minutes to do the basic operations that are needed. We have come to know that the performance has deterirated after the recent release.
Going through this thread IIS 6.0 slowing down one of the suggestions listed was to make sure one destroys objects the code creates which I have taken care in all the pages. Actually all the new changes that were to be done involved working with session or local variables and so no com objects were touched.
We are using Windows 2000 server with SP4 at all the environments. Could someone tell me some suggestions on how to identify the problem? This is a problem faced by many at the clients end and this occurs even on server restart. Please let me know if there are any additional details that are needed.

I've been trying to transition an application from an Access db to an Oracle db. I've got the base functionality down, but it's slooow. I'm prety sure that the 8 processor IIS and Oracle servers are more than capable of the low traffic that my code creates.
My question is, what's the most efficient way to do this? I've been and still am doing research on cursors, locktypes, etc... But, I haven't come across something that is similar, so I thought I'd see if anyone here has had the same experience.
Currently my connections/recordsets look like this: Code:

I have a simple data entry form that has text boxes and some drop-down menus per row. My problem is the performance of the page.
I give the user the option of displaying 25, 50 or 100 rows at a time. Each row has 12 text boxes and 4 drop-down menus. The OPTIONS for the drop-down menus are being populated with data from our MS SQL database.
I'm using VIEWS to get the data and place them in recordsets, but how can I increase performance. It's taking way too long for the page to load and if the user clicks submits.. that takes a long time too.

I am writing a page to go into a real large database and pull out the most recent entry and post it to a web page in an ASP document. I think I have the query right, but it is sooooo slow that it isn't a good solution. The code I have to do the query is as follows, but it is soooo slow it doesn't work..
I have another table which is much smaller, where I can find the unique ID values (they only occur once in the other table..) Can I then go to the last record of the larger table and search backwards from there, stopping when I find the each occurance of each ID in the smaller table?
Any ideas how I might go about it? I have searched and searched but haven't been able to come up with something that works yet. Code:

I have a dynamic datagrid on web application, initially it will populate with search result data. in the first or last column will be a edit button to each row, when the user click this edit, it will allow user to see the column of the row shown as dropdownlist, textbook as defined in the datagrid(or TemplateColumn), after the user make their selection on those fields, the value will be valided and save to database.
My question is when come to make choice to populate the DataGrid, I have concern regarding when to load the Grid(further the Dropdownlist for example). do this inner controls populate with data when the user clicked edit, or do they populate with data when the grid was loaded with the search results? Which one would be more efficient in this case? I intend to hold the Population to the DropDownList until user clicked the row, but would wonder if this approach would work or not? how/when to add the value to the DropDownList.Item.collection?

i'm working on a rather big website project (some movie database you can visit here : URL) so i consider myself an experienced developper in ASP / MSSQL2k and recently i've experienced some nasty problems with simple pieces of code that shouldn't have made any problems at all..
what i can add to my intro is that all the pieces of code work, both on the ASP side and the SQL side, the problem is a dramatic performance loss when everything tries to work together..
so, the thing is pretty simple, i have to make some lists of movies and stuff based a few parameters, filter parameters and sorting parameters..
The whole thing is built in a quite huge stored procedure in order to avoid having msqql compile every different query that can come from every combination of parameters, on the fly.. the stored procedure is very basic, a few "if then else" and the queries and it works perfect. Code:

I've developed an Intranet app that among other things creates form letters using a VB dll, via a cab file, to access Word functions. It works perfectly and performs well when asked to create the Word documents.
However my problem is that it takes >30 seconds for the initial page to display. If I comment out the "<OBJECT>" definition and as a consequence all lines/function referencing that object, the page displays <3 seconds.
The object is defined as:
<OBJECT ID="docobject" CLASSID="CLSID:9735B64A-792C-8167-5912-18A4B729BBA36"
CODEBASE="DOCCAB.CAB#version=-1,-1,-1,-1" HEIGHT="0" WIDTH="0"></OBJECT>
All machines inc IIS are XP Pro,unfortunately,they are also SP2. I believe the security settings are fine as it allows the download of the cab file without pop up and the execution of the dll. The site is set up globally as a trusted site. Should I move to Intranet site?

I had to make a webpage by "modifying" from other www resources script for an intranet calendar page which contain clickable data for different dates from an Access file.
Adaptation successful (after lots of trial+errors) ... but the loading SPEED is over 7 seconds. IIS 5.0. for IE6.0.
How to find out the limits of the asp page?
--- how to find out how many simultaneous hits can it sustains?
--- how to speed it up?
I have read the MS 25+ tips to improve performance & style article but I cannot do much from there and it is not easy to add the response dot flush as the table of the calendar is generated from loops within loops within loops (many if then else).

The default ASP generates the HTML response including several IFRAMES. It takes a long time to load this page. I believe a lot of it is round trips to load the IFRAMES. Couldn't include files be used to increase this performance, so everything is done in the initial call instead of multiple round trips?

I have a big application, about 800 asp pages.
Since we made a few changes, the processor usage on all 4 servers is constantly at 100%. iisreset cures this for a while.
Process Explorer reports that the main hog is the instance of dllhost.exe that manages the application in IIS to which we have made changes to common include files.
It is also racking up Page Faults of 3000 per second (not web page faults, memory faults).
How can I find out which piece of code is causing the processor to freak out so badly? Any tools out there?

I'm attempting to use the MapNetworkDrive <snippedbelow from entire
code below with very poor performance results.
Basically, I have very small 73kb text files that are rewritten daily
to a network share using the MapNetworkDrive command to connect to the
valid servernameshare path.
After successfully connecting the drive in the ASP code, the text file
write process begins and takes more than 15 minutes to write the first
file when the asp page is executed. The process finally times out
since I have set the Server.ScriptTimeOut = 900 for testing purposes
which limits the asp page execution to 15 minutes. In that entire
time, the first file is viewable on the network share but only
partially completed. The additioanl files never complete.
I have done some troubleshooting by manually mapping the share
(outside of the ASP code) using Windows Explorer and copied the same
file that is being created in the routine from the IIS server to the
mapped drive - results are miliseconds to copy - excellent performance
this way.
Any idea of what would cause this performance hit from the looks of my
code? The server is IIS W2K3 and latest version of IIS and updates is
installed. We run many other ASP processes on the server successfully....

I'm currently testing a version of Win2003 to evaluate a migration of our
NT4 server, but I got some troubles with Office Web Component 9 (office
2000), it seems it doesn't work anymore, and I can't find the issue.
When I make a Set objSpreadsheet = Server.CreateObject("OWC.Spreadsheet"), I
got an error :
Server object error 'ASP 0177 : 800401f3'
Server.CreateObject Failed
/test/include/./include_asp/excel-class.asp, line 10
800401f3
So I thought it was a "Web service extension" problem, prohibited por
default by IIS6, I authorized MSOWC.dll but nothing changed...
Then I decided to setup OWC11 and it seems to works fine.... even if I don't
authorized it... (is it a normal behaviour ?, shouldn't I be supposed to
autorized it ? )
I can't understand my problem with OWC9 is there some incompatibility with
IIS6 ? Code:

To provide enriched GUI in .NET Windows Forms can replace ASP.NET Web Forms in a Web Application.
To host/activate a Windows Forms control within Internet Explorer (IE):
1. Create a Windows Forms control
2. Create an HTML document with an object tag that identifies the Windows Forms control
3. Configure the virtual directory for proper activation of the control
4. Configure Code Access Permissions
5. Run the control
.NET Redistributable should be present in the client to run this control in IE.
What will be the performance of a page designed in this manner?
An ASP.NET page (using Web Forms) provides a performance of around 3 seconds over a decent internet link. Will the same be achievable using Windows Forms?
No doubt, Windows Forms provide the best performance for Desktop Applications, but what about in a Web Application as explained above?
This approach is similar to Java Applets. And Applets have failed over the web in time critical applications.
I surfed quited a few .NET related sites (MSDN, gotdotnet etc.) for typical numbers on performance for this kind of page design, but in vain.

I migrated an application from NT4 (IIS4) to 2003 (IIS6).
The application only works when the components are registered with regsvr32.
One of the webpages doesn't work-- when I fill the form out and hit submit I
get "compx error '800af10a' Insufficient memory to perform operation.
/submit.asp, line 283"
I've tried going through and changing permissions but haven't had any luck.
I also tried setting the Web Site to use an Application Pool that I created
to run as System Mode but that didn't make any difference.
Everything works when I select "IIS5 Isolation Mode".
Knowing that it works under IIS5 Isolation mode how can I determine what is
causing the message so I can run it under IIS6?

I migrated a VID6 application from Windows NT 4 to Windows 2003 Server (IIS4
to IIS6) which was developed using ASP and VBScript and I now I am getting an
error message as follows:
Microsoft OLE DB Provider for Visual FoxPro error '80004005'
There is not enough memory to complete this operation.
/hinojosa-web/iPD2.asp, line 377
The line mentioned above refers to the execution of a query to generate a
recordset which will be displayed to the user who is requesting data. This
issue does not always happens, it does only after accesing the web site
several times.
