[TriLUG] tomcat questions

[Steven Blanchard]

Well after some more research, it looks like kaffe does not support
JIT on PPC.  That explains the speed problems I am seeing. Doubling
tomcat's memory got the admin system working.  Maybe the lack of JIT
also causes memory problems

The IBM JVM looks interesting. I am still trying to find the right
combination of buttons to push to download it...

Thanks for the pointers,
Steven
