Hello,

Firefox: i think firefox is a monolith a tab isn't a childprozess (may
be you find a addone, that say you more about firefox)

You are right, the only browser I know of that runs every tab as a separate process is Chrome.

looks on "sar" you can report statistics for a given process (or from
the system)

I would like to be able to exactly monitor programs i/o in the swap
area; 'top' does not seem to be the right tool as processes are sorted
according to the total amount of swap space used, while i would like
processes with high i/o activity (albeit in small amounts) to be
highlighted.

My case is with firefox and konqueror. They stay silently for hours, then
i/o starts, as one can hear that typical noise from the disk and as it can
be checked with 'vmstat'.
Also i would like to locate programs more precisely, to tell which browser
tab, which plugin has triggered that swapping.

Any hints?

Thank you
