Mark,
Yes, it's 32-bit and yes, that's 750 - 1500 CF pages per second. 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
