I have downloaded : J2SE(TM) Development Kit 5.0 Update 5
Linux self extracting file (although I think I should have get the rpm).

I've extrated it in a separate directory and set JAVA_HOME in tomcat to
point to that dir.

Does it make any difference other than the fact that this way it is not
rpm compliant?

This is even worse for my AMD Duron
cache size      : 64 KB

but on the other machine I have :
cache size      : 1024 KB
and still get the same results.
