Here is what I see in TOP: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3345 me 20 0 186m 14m 1860 R 38.0 0.2 3:20.73 perl 3282 me 20 0 186m 13m 1844 R 33.0 0.2 3:27.73 perl 3255 me 20 0 186m 14m 1848 R 27.4 0.2 3:22.05 perl 3314 me 20 0 270m 98m 1892 R 27.4 1.2 2:31.70 perl 3262 me 20 0 186m 13m 1848 R 27.1 0.2 3:24.75 perl 3268 me 20 0 200m 27m 1892 R 26.8 0.3 3:10.74 perl 3302 me 20 0 186m 13m 1848 R 25.4 0.2 2:50.10 perl 3290 me 20 0 241m 68m 1892 S 24.1 0.9 2:59.26 perl 3011 me 20 0 667m 46m 8244 S 21.5 0.6 1:43.02 mysqld 3187 me 20 0 987m 48m 8572 S 20.2 0.6 2:12.45 mysqld 2953 me 20 0 923m 52m 8496 S 19.2 0.7 2:15.93 mysqld 3006 me 20 0 667m 55m 8028 S 17.2 0.7 1:49.98 mysqld 2967 me 20 0 677m 53m 8132 S 16.6 0.7 1:35.39 mysqld 3011 me 20 0 667m 46m 8244 S 16.2 0.6 1:42.37 mysqld 3010 me 20 0 667m 46m 8140 S 15.9 0.6 1:30.93 mysqld 3017 me 20 0 677m 46m 8112 S 13.9 0.6 1:38.93 mysqld 3086 me 20 0 667m 47m 8052 S 10.3 0.6 1:23.74 mysqld 3012 me 20 0 1051m 55m 8708 S 8.6 0.7 0:52.48 mysqld 2949 me 20 0 1051m 55m 8884 S 7.6 0.7 0:29.10 mysqld 3327 me 20 0 186m 14m 1708 S 4.6 0.2 0:24.42 perl 3280 me 20 0 186m 12m 848 S 1.7 0.2 0:08.53 perl 3260 me 20 0 186m 12m 848 S 1.0 0.2 0:08.54 perl 3253 me 20 0 186m 12m 848 S 0.7 0.2 0:06.89 perl 3300 me 20 0 186m 12m 848 S 0.7 0.2 0:06.87 perl 3288 me 20 0 186m 13m 848 S 0.3 0.2 0:02.51 perl 3312 me 20 0 186m 13m 848 S 0.3 0.2 0:02.06 perl 3343 me 20 0 186m 13m 848 S 0.3 0.2 0:02.74 perl As you can see, we're loosing a lot of CPU on Perl. Maybe we can do things to tune it? Two example threads: http://www.webmasterworld.com/forum13/1575.htm http://www.ccl4.org/~nick/P/Fast_Enough/ --
