I'm trying to run a simple test on a pair of Linux 2.4.2 PC's that starts up simultaneous netperf tcp stream tests, and find that I cant invoke more that 800 without running into memory allocation failures. This wouldnt be strange except that I find on the same systems, FreeBSD seems to do twice as well (1600). I complete 500 concurrent netperf tcp stream tests sending 64 byte packets successfully, but again, FreeBSD completes a 1000 successfully. Also, Linux appears to hog around 300MB on the server side, whereas FreeBSD only appears to be using 3MB. Those are the bare numbers, details available, of course, but what I'd like to do is repeat the Linux test with 2.4.4 and include some VM patches that might possibly alleviate any memory management issues I may be running into. This is between a 500MHz PIII Katmai and 333MHz PII Deschutes both with 512MB memory, over a 100Mb (3C905C) private nw. I'd appreciate any pointers to patches that might help, or suggestions in general to improve the Linux numbers. Especially any insight into whether this is a case of apples/oranges or whether I'm missing some trivial element here... I know of Ed Tomlinson's patch posted on this list on 4/12, are there any others? I know Jonathan Morton posted some OOM patches, are those included in 2.4.4? thanks, Nivedita --- Nivedita Singhvi (503) 578-4580 Linux Technology Center [EMAIL PROTECTED] IBM Beaverton, OR [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
