Aaron is right -- Webware has no problem executing as many simultaneous requests as the number of threads you are running -- UNLESS you are using an extension library that fails to release the global interpreter lock while it runs. It's possible the Sybase module you are using doesn't release the GIL when it should, although that seems unlikely to me.
You might also consider increasing the minimum number of threads in the AppServer.config file from 5 to something higher, if you expect many of these long-running requests to happen at the same time. You might also implement some mechanism to prevent additional long-running requests from starting while the server is heavily loaded -- for example if you have 10 threads, you might want to ensure that no more than 5 of them are being used for long-running requests at a time, to keep the other 5 available to handle the quick requests. - Geoff -----Original Message----- From: Aaron Switzer [mailto:[EMAIL PROTECTED] Sent: Friday, February 24, 2006 9:12 AM To: webware-discuss@lists.sourceforge.net Subject: Re: [Webware-discuss] Performance on long-running pages Leigh, What's the CPU load like when the reporting page is being accessed? I have something similar in one of my projects and had to introduce caching for the reporting pages due to the way it would hammer the CPU (99% usage for upwards of 10 minutes). Luckily I have the application running on a dual processor machine, so the second processor would be available to handle further incoming requests. I'm still running Webware 0.8.1 myself and have found the only limitation to handling simultaneous and long running requests is CPU availability.
