Hmmm, 200,000 files 1,000,000 iterations. On avg, each file hit five times. Uhh, that's not a good way to avoid caching. Doh. Wow, caching is pretty amazing. I just reran the program, this time using 500,000 file paths and only stat'ing 10,000 of them. The first run was 99,059/second, the second was 188,239. So I guess 100,000/second is about right on my system w/o cache. m _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "[EMAIL PROTECTED]"
