Fully realizing that the plural of "anecdote" is not "data," I can report that enabling HT and running an SMP kernel speeds up parallel make operations by 15-20%. E.g., running "make -j2" on P4/HT/SMP is slightly faster than "make -j2" on the same processor running a UP kernel. It seems like the SMP kernel is better able to keep the core busy than the UP kernel. Other operations, particularly day-to-day desktop stuff, seemingly don't benefit much at all. -- Paul Heinlein <> heinlein at madboa.com <> www.madboa.com
