Thanks Wil,
I have actually been doing a fair amount of tuning the JVM. I'll definitely
read your article, but in the meanwhile, here's my jvm.config file. Let me know
if it seems totally wrong:
#
# VM configuration
#
# Where to find JVM, if {java.home}/jre exists then that JVM is used
# if not then it must be the path to the JRE itself
java.home=C:/j2sdk1.4.2_16/jre
#
# If no java.home is specified a VM is located by looking in these places in
this
# order:
#
# 1) bin directory for java.dll (windows) or lib/<ARCH>/libjava.so (unix)
# 2) ../jre
# 3) registry (windows only)
# 4) JAVA_HOME env var plus jre (ie $JAVA_HOME/jre)
#
# Arguments to VM
java.args=-server -DJINTEGRA_NATIVE_MODE -DJINTEGRA_PREFETCH_ENUMS -Xms1024m
-Xmx1024m -Dsun.io.useCanonCaches=false -XX:MaxPermSize=128m -XX:PermSize=64m
-XX:NewSize=48m -Dcoldfusion.rootDir={application.home}/../
-Dcoldfusion.libPath={application.home}/../lib -XX:+UseConcMarkSweepGC
-Dcoldfusion.classPath={application.home}/../lib/updates,{application.home}/../lib,{application.home}/../gateway/lib/,{application.home}/../wwwroot/WEB-INF/cfform/jars,c:\\CfusionMX7\\classpath
#
# commas will be converted to platform specific separator and the result will
be passed
# as -Djava.ext.dirs= to the VM
java.ext.dirs={jre.home}/lib/ext
#
# where to find shared libraries
java.library.path={application.home}/../lib,{application.home}/../jintegra/bin,{application.home}/../jintegra/bin/international
system.path.first=false
#
# set the current working directory - useful for Windows to control
# the default search path used when loading DLLs since it comes
# before system directory, windows directory and PATH
java.user.dir={application.home}/../../lib
# JVM classpath
java.class.path={application.home}/servers/lib,{application.home}/../lib/macromedia_drivers.jar,{application.home}/lib/cfmx_mbean.jar,{application.home}/lib
