I'm using IIS 7.5 with PHP and I'm having troubles with my application, it is VERY slow and it can take more than 30 seconds to respond sometimes.
I believe this is due to some kind of queue of requests to process.
I've taken a look at the "Worker Processes" menu in IIS and I found out there are tends of request in the DefaultAppPool. I though servers could handle hundreds or thousands of requests, so I'm a bit surprised to find out the server slows down so much with just a few tens of requests.
Is this normal?
