I'm curious what Mac OS X users are finding most useful for profiling
their applications. Right now I'm mainly interested in CPU profiling
because I trying to understand why JEditorPane is so darned slow on Mac
in displaying HTML.
I have experimented running with -Xrunhprof:cpu=samples and
-Xrunhprof:cpu=times. When doing the later, I get a continual stream
of
HPROF ERROR: method on stack top != method exiting..
printed on the console. Not sure why. This makes the app run so slow
that I can't even get to anything interesting.
If I use the cpu=samples, I get some (seemingly) valid output, but
can't make much of it. I have tried viewing the output in HPjmeter but
this hasn't been too enlightening.
At another company I used to work for I used JProbe to look at this
stuff. I can't afford this right now. Are there other alternatives?
As an aside, I have narrowed down most of the time with HTML display to
validating the layout (basically laying out the text). I suspect the
time sink is in getting Font information, since the delay seems
proportional to how many fonts are used in the HTML.
