Here is my config file:( we have 1.5 G of ram - The funny thing is we
have about 1 concurrent user on average)
#
# 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:/CFusionMX7/runtime/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
-Xms768m -Xmx1000m -Dsun.io.useCanonCaches=false -XX:MaxPermSize=256m
-XX:NewSize=256m -XX:PermSize=128m

# commas will be converted to platform specific separator and the result
will be passed
