I have downloaded FreeBSD 3.1-RELEASE and applied Matthew Dillon's patch postes very recently. Here are my results: # date; time find -x /usr/src > /dev/null; date Wed Apr 21 19:45:06 GMT 1999 0.255u 0.841s 0:30.75 3.5% 21+317k 2284+0io 1pf+0w Wed Apr 21 19:45:37 GMT 1999 # date ; time find -x /usr/src > /dev/null ; date Wed Apr 21 19:45:42 GMT 1999 0.328u 0.476s 0:02.62 30.1% 25+377k 0+259io 0pf+0w Wed Apr 21 19:45:45 GMT 1999 The first time I run find command, the time elapsed is 30 seconds, comparable to the kernel without patch. The second time I run find command, the time elapsed is only 2 seconds. And if I interprete the output of time correctly, the first time we did 2284 I/O read, 0 I/O write. The second time we did 0 I/O read, 259 I/O write. If I am wrong, please correct me. The machine is Pentium 233 with 64M memory. I did this test via a remote log in. -Zhihui To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
