RESOLVED DUPLICATE of bug 774330

Details

Inner-loop-type JS-heavy workloads are destroyed by the JS profiler; compare http://conduit.bitops.com/~vladimir/misc/darkroom/darkroom.html with profiler enabled (0.5fps) and disabled (17-20fps).  Note that it's slow to begin with (that's bug 774433), but it's unusable with the profiler enabled.
Do you see this on Windows?
Yeah, with today's nightly build
Confirmed, cc'ing Alex.
