I could reproduce the problem with my Athlon running 32-bit linux (1 Gig
of RAM, JRE1.5.0_04 from Sun).

The applet is consuming 100% of my cpu, slowing down mouse movement and
draining overall performance. This does not look like typical memory
problems (no swap access, steady performance drain instead of periodical
total blocks etc.) It happens regardless of how big I set the -Xmx
parameter.

No net access. It just looks like the CPU. I don't got these problems
running Java under Windows (JRE1.5 from Sun, Firefox too)

renicing the java process helps. It still consume 100% CPU, but now the
rest of the system is not involved.


Ciao, Imi.

PS: Maybe someone move this to bugzilla?

PPS: To Johnny: Open a root-shell and start "top". Then press r and 
enter the id of the java_vm - process (the top one ;). Then renice it
to priority 20. This helps as a quick fix.
