In general (and this is an area I do know a little about!) performance on a non-memory starved machine will be the same between 32-bit and 64-bit OS installs (as largely backed up by those links). On the plus side you're getting a slight benefit with 64-bit due to not running the compat layer, on the negative side you're reducing cache efficiency and hitting memory harder. Having said that, tasks like media encoding (see the benchmarks in your links) will show more interesting differences as they stress very specific areas of performance (for example high precision float math is MUCH faster on 64-bit). IMHO (YMMV) for general computing (which includes running SC) there's really no difference unless you want >3GB RAM. -- radish http://www.last.fm/user/polymeric ------------------------------------------------------------------------ radish's Profile: http://forums.slimdevices.com/member.php?userid=77 View this thread: http://forums.slimdevices.com/showthread.php?t=65585 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
