Hi Robert,   Just wondering, how did you see that there were times when 11-15 threads would be better?  What were you looking at that gave that away?   Thanks!

I started with 10, and saw that there were times when 11-15 threads would be used by my users, so I increased it to 15. I suspect that should my sites get busier, I would need to go to 20. I would not go above 25, but rather look to adding more servers/services.   Typically my max threads is around 10 now. I have one service at 9 after 3 days of uptime. Since the max number of active threads since service inception is a measurement you can get from @serverstatus, I like to regularly monitor that value to see what I�m using.   Robert   -----Original Message----- From: Chuck Lockwood [mailto:[EMAIL PROTECTED] Sent: Thursday, July 01, 2004 11:37 AM To: WiTango-Talk Subject: Witango-Talk: threadPoolsize - 5.0.1.065   I and a few esteemed colleagues were stress testing an application and found that we could hang the server if we had the threadPoolSize set high and did enough large database queries at once to cause most or all of the threads to be used. However, if we lowered the threadPoolSize, Witango queued the additional requests instead of trying to run them all concurrently and everything finished fine.  In other words, it worked exactly as the documentation states.   The question becomes, how do you intelligently set the threadPoolSize based on server memory and processor power without �guessing� at a reasonable upper limit?    Thoughts?
