One quick-and-dirty way to check threads for any process is to use the ncurses-based 'htop' utility. I much prefer this to 'top' for several reasons, including its ability to hide/display kernel threads, hide/display user threads (in a different color if you like), display with vertical and horizontal scrolling, assign processor affinity on the fly, ptrace/strace processes, and a lot more. It's in Dag Wieers' rpmforge repository for CentOS. The suggestions offered in this discussion are all very useful with regard to tuning Apache. Chuck
