One of the big breakout moments for Linux was when IBM added SMP support. Before then it was never useful for anything "serious" or commercial generally speaking.
Linux was a really nice hobby before then.
- kazinator 7y agoI used SMP in 1995, using a 1.3 kernel. Board was an Asus with two 100 MHz Pentiums. I saw about a 35% speedup on a "make -j 3" back then; there was a lot of coarse-grained locking still (BKL), and the hardware wasn't good to begin with. I'm pretty sure IBM had nothing to do with Linux; the name that comes up in my mind when I think back to that time is "Alan Cox", not "IBM". I did contract work for infomine.com in 1994; it ran on Linux.
