well, once we had some performance-problems on a TRUE64-Unix, on a
32bit-Linux everything ran smooth.

We logged the garbage-collector with

java -Xloggc:<file>

and compared the output (you will have to use the same requests on
both machines to make it comparable, JMeter was very helpful here).

If some differences occur, you might be able to adapt the
garbage-collector (-Xincgc)

And now comes just a shot from the hip:

If the used JVM supports it, maybe you want to give
"-XX:MaxPermSize=128M" a try and see if it helps.
