>Basically, I soon as I launch the test, I can see the task manager showing w3wp.exe increasing its amount of memory used in a constant manner. Basically, it goes from 10000k to 100000k and it increases in a regular way until the IIS runs out of memory. This is really irritating. I am only launching 8 transactions at the same time which takes about 0.5 second to execute. This is making no sense. One page on the net recommended to update to the latest service pack but the server is already up to date. The increase of memory is done within a period of 20 minutes approximately. So, by the time I started to write this message, the memory took by the process as moved from 100000k to 225000k. Anyone would know where I should look for to resolve that issue?

Aren't there settings in IIS that let you limit the maximum memory it can use?
