Been doing some testing on other Tomcat applications I have with BEA's JRockt 5 JVM and have replaced j2dsk with jrockit.
BEA claims 30% performance improvment over Sun's JVM.
See http://www.bea.com/framework.jsp?CNT=in ... s/jrockit/
Scalix CE's web-services seem to be faster with less memory allocated to jrockit (compared to Sun: See JAVA_OPTS). This was purely a subjective test. I have no hard data (yet) to support "faster"!
Any other experiences out there???
