Please define "performing much better" ?
For our app benchmarks, JDK 1.4 GC was substantially better than PERC
3.3.

Check out perc 3.3 at http://www.newmonics.com/info/gc.shtml, it has a
pretty decent GC performing much better than Sun's. Also IBM's JVM is pretty
good too.

This is
I am not aware of all the performance implications of
this, but it should be possible to create a Thread to
run on some interval you define which just infinitely
loops a call for garbage collection (gc() right?) then
goes back to sleep until next iteration.
At least then you can control how often
ing abouts eden, young,
old generations. Some options are XX:SurvivorRatio and
XX:SoftRefLRUPolicyMSPerMB

Hi all
I am running tomcat 4.0.1 with virtual hosting and was wondering how much
memory to allocate to each additional host. By default, we use 64M for one
host but adding another 64M for second host seems excessive considering it's
the same tomcat instance.
However, if we add a lot the JVM will u
