One of my friends who is a zealot in the Linux camp recently sent me this article that he pulled off their kernel mailing list. It's from "mr. lmbench" Larry McVoy: I've been stress testing for the last day or so because I added a 128MB DIMM and started getting crashes (turns out it is a known problem with the FIC 503+ MB, so get the biggest DIMM you can afford - it doesn't seem to like two of them at once). I'm sitting at the system, which is currently doing the following - running X, with an xfishtank & xearth in the background, the fish are moving, albeit slowly - running a "make -j 24" on the kernel - running a "tar cf - . | cat /dev/null" of my home directory, which is NFS mounted, so lots of network traffic - running "scrubber 120" which is a program which allocates 120MB of memory and then walks through it over and over, checking and setting values (this found "bad" memory when I had 2 DIMMS in). I'm running in 128MB total, and this program has an average RSS of 100MB - running lat_pipe and bw_pipe in background, in an infinite loop - running top to watch all this And the system is, while sluggish, responsive while I'm typing. I've opened up windows during all of this and it works, again, sluggish but not so sluggish that you give up. You could actually get work done on a system this busy. I'm very impressed - I do not think that SunOS (or any of the other Unices) ever got to this point. If you did this to them, it was just intolerable. So whatever you did, it's worth it. Quite impressive, actually. Not that, in the grand scheme of the planet, it REALLY matters, but what sorts of "stress tests" do people routinely pull out of -current or more importantly 3.1-stable? I still have a lowly 486 (upgrading RSN :), but I've had more things running at 1 time under X than I thought possible for a 486 (I used to "stress test" OS/2 by starting up gobs of things and it would eventually require a reboot to come back to normal). It would have been nice had he told us what CPU he was using--but I just have to believe that FreeBSD is on par with this "impressive" (well it impressed him) Linux achievement.
