GUADEC dtrace, normalized time spent in Cairo
Friday Jun 30, 2006
Those attending the GUADEC performance bof may be interested in this little dtrace script based on normtime.d:
#!/usr/sbin/dtrace -s
#pragma D option quiet
BEGIN
{
/*
* Get the start time, in nanoseconds.
*/
start = timestamp;
}
pid$target::*cairo*:entry
{
@func[probefunc] = count();
}
END
{
/*
* Normalize the aggregation based on the number of seconds we have
* been running. (There are 1,000,000,000 nanoseconds in one second.)
*/
normalize(@func, (timestamp - start) / 1000000000);
}
run it with cairo.d -c gedit and play with gedit:

When I have more time I'll try this on the benchmark and also try it in a thin client environment where I expect things will be different. But now it is time for lunch!
