See: . As for multicore support, I thought it was better with -CURRENT (ULE2 as of late sounds like it can support concurrency with multiple cores / CPUs better than the 4BSD scheduler), but running -CURRENT comes with a price, namely stability. The GNU/Linux crowd (or at least some folks in it), were raving that later versions of gcc, i.e. 4.x (coming to 7 sometime in the near future maybe) had better multi - core / CPU support as well in terms of optimizations and junk. But that's just fanboy/ricer ranting, maybe.. or maybe not.. -Garrett
