Hi Everyone,
We have recently put together a new CF server, moving from 32 bit, 4Gb RAM
Windows over to 64bit, 16Gb RAM Windows.
We have pretty much done a default set up, and placed the same set of
applications on the new server, and have run in the machine for a bit. After
a few weeks we have been noticing some cracks appear, and we now have some
issues that we have narrowed down to the JVM/CF setup.
Here is the setup on the old and new boxes:
4GB, Dual Xeon, 32bit windows, jdk1.6.0_13
java.args=-server -Xms512m -Xmx1000m -Dsun.io.useCanonCaches=false
-Dcoldfusion.fckupload=true -XX:PermSize=128m -XX:MaxPermSize=240m
-XX:+UseParallelGC -XX:+HeapDumpOnOutOfMemoryError
-Dsun.rmi.dgc.client.gcInterval=150000
-Dsun.rmi.dgc.server.gcInterval=150000
-Dcoldfusion.rootDir={application.home}/../
-Dcoldfusion.libPath={application.home}/../lib
-Dcoldfusion.classPath={application.home}/../lib/updates,{application.home}/../lib,{application.home}/../gateway/lib/,{application.home}/../wwwroot/WEB-INF/flex/jars,{application.home}/../wwwroot/WEB-INF/cfform/jars
Crashed a lot, had out of memory issues once every hour on a good day.
www.hairbodyskin.com.au takes 2,781ms (from FusionReactor)
16Gb, Quad Core, 64bit Windows, jdk1.6.0_13
java.args=-server âXmx8192m -Xms8192m -Dsun.io.useCanonCaches=false
-XX:MaxPermSize=1024m -XX:+UseParallelGC -Xbatch
-Dcoldfusion.rootDir={application.home}/
-Djava.security.policy={application.home}/servers/cfusion/cfusion-ear/cfusion-war/WEB-INF/cfusion/lib/coldfusion.policy
-Djava.security.auth.policy={application.home}/servers/cfusion/cfusion-ear/cfusion-war/WEB-INF/cfusion/lib/neo_jaas.policy
Runs great, has no crashes, happily inside memory limits, but runs so slow.
www.hairbodyskin.com.au takes 10,361ms (from FusionReactor)
I must add that this is NOT the only application on this server, there are
many others, mostly built on the same code base, some older some newer.
I would like some advice on how to better adjust my settings - I think this
should be reasonably for those educated in the art because we are talking
(in some cases) a 5x difference in execution speeds. I am thinking:
1) increasing GC interval to 600000
2) fixing max and min perm size to 1024
3) putting xms down to 4096
Are these sensible? Any other suggestions?
Thanks in advance!
