Attached file Python profiling script (obsolete) —
Some tools for profiling IPC messages can be useful. The attached python script lists messages by number and latency.

Attached patch Patch v2 (obsolete) — — Splinter Review
Turns out that since the parent and child outputs go to the same place, they can overwrite each other, dropping or cutting lines in the middle. So, added an option to redirect the child stdout or stderr to a separate file. Example output (icanhascheezburger/fennec): http://pastebin.mozilla.org/790209

Now with visualization as well.
Attachment #475941 - Attachment is obsolete: true
Updated patch (see link in comment 6) now supports profiling on android devices. See comments in android_prettifier.py for details. Will post some profiling data in bug 629513 soon.
This is very obsolete.
