In both runs the same computations are done (sequentially resp. parallel), so the gc should be the same. But still using 2 cores is much slower than using 1 core (same program - no communication).
The same GCs are done, but GC has to be done on a single core (currently; parallel GC is in development) so you will see a lot more lock contention when the GC kicks in. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
