What is the query?

"20x" means 20 concurrent testing processes, right?

Interesting (and surprising that the performance differential is that
large, to me at least). Can you tell if the performance gain comes from
an improvement in a particular subsystem? (i.e. could you get a profile
of Sun/gcc and compare it with Sun/sunsoft).
