process vs threads


Hi, anyone knows how I can distinguish whether I'm looking at a process or a thread when I issue "ps -ef"? Reason I'm asking is in Apache, I can configure the MPM to use prefork or worker. Whenever new connection is required, prefork adds an additional process, whereas worker adds an additional thread to the process.

You need the 'L' flag, ps -eLf

(NLWP is number of threads; LWP is thread ID.)

There is not much of a performance difference between a process and a thread in Linux (from what I've read).
