I actually haven't done any benchmark on 2.0.0 (slap on wrist) yet - will
do so when I get into work. Based on the pre2.0 kernels (and my memory:)
), most of the code in a single process executes about 5% slower, but with
next to no degradation in performance if two identical processes are
running simultaneously. I'll do some proper tests and post them here.
