Paul, These settings are in line with what I would expect and implement myself. I don't have much to criticize here - but I will noodle with you :)
You have Simultaneous requests set to 50. Check your proc usage you might be able to go a touch higher if you have 8 cores - say 64 or 72 ... but only if they show as underutilized. Modern procs sometimes have a lot of unused horsepower - but you would know that by watching, and every application is different. You say your heap is 1088 but I don't see xms or xmx args in your server args. That's all I got. All in all I'd say you might be doing about as well as expected on a 32bit standard machine.

Typically a request hits the following CF templates. * application.cfc * header.cfm * mainpage.cfm * footer.cfm The page speed warning level is set to 5 seconds so I can see what's holding things up quite easily. The job search is the thing that regularly triggers the limit... However, it's not too bad given the amount of searches going on and typically they complete in 5 seconds or slightly less. E.g. processing template: <pathtosite>\www\jobsearch.cfm, completed in 5 seconds, exceeding the 5 second warning limit In terms of HTTP hits per second, then I'd have to double check but HTTP hits per second will be much, much higher. The DB is MSSQL Server, *all* queries are effectively prepared statements and use CFQUERYPARAM everywhere. The sites make extensive use of "CachedWithin" and most queries have execution times of 0 according to the SQL profiler. The server has the following Config settings: Simultaneous Template requests: 50 JVM Heap Size : 1088MB JVM arguments: -server -Dsun.io.useCanonCaches=false -XX:MaxPermSize=384m -Xmn256m -Dcoldfusion.rootDir={application.home}/../ -Dcoldfusion.libPath={application.home}/../lib -XX:+UseConcMarkSweepGC -XX:+UseParNewGC Caching: 8200 templates (more than enough) Trusted Cache is on Save Class files is enabled Max. Cached queries: 750 Sessions: J2EE sessions are enabled and have a max. timeout of 30 minutes Paul ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:355915 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
