Speeding up Sakai on dual-core machines

On a related note, I tend to run this collector:
This is the sun recommended one for server class machines (which dual
cores should be close to) and it uses ergonomics (which is the
autotuning stuff in the JVM) to optimize performance and memory usage.
That said, the theory of JVM tuning and the reality do not always
agree. I am curious to know if this uses more memory or starts up
faster or what compared to your old settings and would like to know
what your old settings were.
