In fact, the load averages are so irrelevant now that I barely pay attention to them. The server goes to 4 or 6 load averages without slowing down, and other times the load average would be 0.8 and the server is running slow. An example of unmatching TOP: last pid: 17889; load averages: 0.60, 0.52, 0.50 up 3+17:22:33 00:41:45 186 processes: 2 running, 183 sleeping, 1 lock CPU states: 30.0% user, 0.0% nice, 1.7% system, 0.1% interrupt, 68.3% idle Mem: 1678M Active, 1110M Inact, 287M Wired, 87M Cache, 112M Buf, 103M Free Swap: 8762M Total, 1584K Used, 8760M Free PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU CPU COMMAND 5071 nobody 101 0 43124K 35180K CPU2 2 0:07 14.89% 14.89% httpd 14409 nobody 4 0 43940K 36076K sbwait 0 0:01 1.22% 1.22% httpd 95515 nobody 4 0 39892K 32188K sbwait 1 0:08 0.29% 0.29% httpd 17656 prpcon 4 0 9916K 5680K sbwait 1 0:01 0.26% 0.24% cppop 18006 root 8 0 3032K 2324K nanslp 0 25:35 0.05% 0.05% perl 783 root 96 0 9704K 4572K select 3 17:39 0.05% 0.05% cppop 3820 mysql 20 0 339M 251M kserel 3 43:34 0.00% 0.00% mysqld 744 root 8 20 16776K 15120K nanslp 0 40:53 0.00% 0.00% perl 72899 root 20 0 21704K 20128K kserel 3 30:25 0.00% 0.00% clamd 913 root 97 0 11616K 4864K select 3 5:27 0.00% 0.00% cpsrvd 1065 mailnull 96 0 5880K 2828K select 0 3:22 0.00% 0.00% exim-4.62-0 _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
