>I have fine tuned the IIS application pool setting in the last two days and the current settings seem to have increased a lot the performance of the application. I have enabled 5 worker processes and adjusted some settings. So far, after 5 hours, the application responds much faster and I haven't seen one transaction that was taking too long. The average respond time is now at 0.35 second.

If you would not mind, can you list your settings? We're playing here with session timeout and I was reading some information about it, but I would appreciate if you can give me some information that helped you.

I agree, today's response is better than yesterday's and two days ago.
