Ajas, besides what Steve has rightly recommended, I'm curious about your observation of how the req/sec went "as high as above 24" but the "max simult requests is 8". Just to be clear, the hitting of 24 does not mean that somehow FR is reporting more than should be possible. As you note, that (the dark blue) is reqs/sec, and you could have many reqs that run in less than a second (and I'm pretty sure that average is calculated for all requests executed over a 5 second span). So you could hit 24 and still be only running in the 8 request slots.
Notice instead that the gray or light blue (when it's under the dark blue) is instead the number of "active requests" running at each 5 second intervals. You'll note that that never does go above 8 in your reports. So as to whether you should increase it, a factor would be if you found FR reporting that you were ALWAYS at or near that limit, because then naturally any requests that couldn't run would now be queued (by CF, which is not viewable in FR but instead in either CFSTAT [on any version of CF except for multiserver deployments] or the Multiserver Monitor [in CF 8/9 Enterprise/Developer]). If you consistently have lots of queued requests (or FR showing always the active requests count near your Simultaneous requests number), those people are then waiting to run, and as Steven says, if your box is up to the task, you could try to let more of them run at once. Hope that helps. /charlie From: [email protected] [mailto:[email protected]] On Behalf Of Ajas Mohammed Sent: Tuesday, July 20, 2010 10:52 AM To: [email protected] Subject: [ACFUG Discuss] CF 7 - Maximum number of simultaneous requests Hi, I am attaching a snapshot of FusionReactor's system metrics page which shows no. of requests/sec. Recently, it went to as high as above 24. We use CF 7 on Windows Server 2003, Intel Xeon CPU E5450 @ 3.00 GHZ, 3.99 GB of RAM and the setting for Maximum number of simultaneous requests is set to default 8. We have not changed any JVM Memory settings. The Minimum JVM Heap Size (MB) is blank and Maximum JVM Heap Size (MB) is 512. Anyone wants to share their thoughts on the setting for Maximum number of simultaneous requests, Maximum JVM Heap Size (MB) or any general suggestions? Is it ok to up the Maximum no. of simultaneous requests? Thanks, <Ajas Mohammed /> http://ajashadi.blogspot.com We cannot become what we need to be, remaining what we are. No matter what, find a way.
