A while ago (I think more than a couple of years ago now), Vlad
implemented FunctionTimer which is a facility to time how much each
function exactly takes to run. Then, I went ahead and instrumented
a whole bunch of code which was triggered throughout our startup
path to get a sense of what things are expensive there and what we
can do about that. That code is hidden behind the NS_FUNCTION_TIMER
build-time flag, turned on by passing --enable-functiontimer.
Is any of the instrumentation worth turning into instrumentation for
the new profiler (SAMPLE_LABEL_* macros)?
Otherwise sounds fine to me (though there could be somebody using it
who wants it to stay).
I'd like to remind people of the existence of the JS performance timers
(js/src/perf). Appears never to have gotten an OSX or Windows back end,
but really ought to get used more than it does.
