Not just 'sortof' good but it appears it's unconditionally good:
meanwhile other testers have reproduced the single-JVM speedup
with the latest numa/core code as well, so the speedup is not
just on my system.
Please post your kernel .config so I can check why the 4x JVM
test does not perform so well on your system. Maybe there's
something special to your system.
Thanks,
Ingo
