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.
