Profiling inspections
Running "Analyze Code…" with the default profile on my project takes around 1h 30m to finish. This is on a MacBook 2GHz with 2G RAM.
It seems I need to turn off a lot of inspections to bring this down to a manageable time, but I'd like to know which inspections would really make a difference. Is there any way to find out how much time each inspection contributes to the total running time?

There is no easy way currently. But you can try and "capture cpu usage data" and post the file somewhere I can get at it and I can tell you what inspections take up the most time. That info would also be very useful for me, because that way I know what inspections to optimize.

By the way, of course I do not need CPU usage data for the entire 1 and a half hours. Half a minute should be more than enough.

But then, the "Inspecting Code" dialog is modal, so I can't turn off the cpu profiler while it's running…
Hmm… I remember that somewhen during the last EAP, Dave released an InspectionGadgets build with a "debug" panel that showed run times for all enabled inspections. It would be nice to have something like that again, this time for all inspections, not only InspectionGadgets.
Your memory is fading. That panel hasn't been there since 4.0, IIRC.

Agh! It's really been that long?
Cancel the inspection process and quickly turn off the profiler.

Ironically, a change in the inspections API to make them run more efficiently has made it impossible to measure the runtime of the InspectionGadgets inspections. I have a request open for this: http://www.jetbrains.net/jira/browse/IDEADEV-8716
A way to show the runtime of all inspections would be better. Perhaps something like the statistics tab for unit tests. Post a request and I will vote for it.

Hello Bas,
For what it's worth, measuring inspections runtime got even harder in Selena
- we now support running parts of the inspections pass in parallel using
different CPU cores on a multi-core/multi-CPU machine.

I need more cpu's in my machine!
Excellent! My dual core laptop investment just payed off!
