One place that Rob and I still haven't found a good solution for profiling is trying to work out whether we should be focussing on optimising our mod_perl code, or our IMAP config, or our MySQL DB, or our SMTP setup, or our daemons' code, or... Can anyone suggest a way (under Linux 2.4, if it's OS dependent) to get a log of CPU (and also IO preferably) usage by process name over some period of time? Sorry to move slightly off-topic here, but in optimising our mod_perl app we have to work out which bit of the whole system to prioritise.
