Just to see what would happen on my machine (everyone else was doing it...and no bridge analogies, eh? *grin*)...I tried doing a 'make -j3' for a compile... according to 'time', with -pipe, it came out faster in user/system time and, what I'm assuming, in actual time. What I'm curious about is what exactly does this do? According to the man page, it basically does 'parrellel makes', correct? But if I watch the make process, it doesn't look like more then one file is being compiled at a time...so, on a single CPU system, what does it do to produce a benefit? Marc G.
