I have a website that is asp (not .net) based with an Access DB and I am in the process of replacing an old windows 2000 server with a much faster windows 2003 server. Here lies the problem I have a script as part of the admin that exports data to a csv file. The query joins 4 tables together to get the data needed for the export. On the windows 2000 server it takes 1-5 seconds to execute and have the csv file ready for download. On the window 2003 server it times out. I striped it down to use 2 joins and it worked although it took more like 10-20 seconds to export. This exports a specific range of ID's and the range is normally only 40-50 rows. If I put time stamps in the code the problem is in the query of the database, so I know its not in the file write etc.
I am going to rewrite it to use multible querys instead of one large query, but I have many other sites that I am moving to this server that would work better if I can figure out why it is so slow.
The windows 2000 is a 900 mhz server the windows 2003 is a 2.8GHZ server both have 1 GIG of ram. The database file is on the local drive on both servers. I am guessing it is a difference in the Jet version, I just haven't been able to find a solution to the problem. This uses a DSN connection, configured the same on both servers. I have also tried it as a DSN-less connection with the same result.
I have installed access on the server and to execute the command in access it is <2 sec.
I am not an access expert I normally program in .net and php and use MySQL and MsSQL for databases, we just have these legacy sites that use Access DB's
