I think it's well-known Solaris exploits multicore better than Linux or BSD. I see quite a few problem reports on the various BSD SMP mailing lists. I don't track Linux very much but I can see from conky on my boxes Linux just doesn't do that well. And race conditions are unfortunately an ongoing problem in many apps. I work on a different platform where multithreading and multiprocessing were a very early part of the design and I have seen a big difference in performance and lack of race conditions in that environment because it was based on a native multithreading model whereas UNIX was based on process forking and threading came much later and you could argue was not exactly implemented seamlessly. It's not an apples and apples comparison but the difference in software issues on those systems is night and day. As far as I can see those problems still haven't been resolved at the design or implementation levels. _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
