This looks great!

By the way, you might find it easier to run all of the benchmarks in one go using Tools/Scripts/bencher.  You need two checkouts, which you build separately: one for baseline (no changes), one with your changes.  You also need ruby installed, and the json gem.  And a ~/.bencher file.  When you run bencher the first time, it will tell you how to set this file up.

Then do:

Tools/Scripts/bencher TipOfTree:<path-to-baseline-jsc> MyChanges:<path-to-your-jsc>

Example:

Tools/Scripts/bencher TipOfTree:/Volumes/Data/pizlo/OpenSource/WebKitBuild/Release/jsc CFA:/Volumes/Data/pizlo/secondary/OpenSource/WebKitBuild/Release/jsc

I find that this makes it a bit faster to run benchmarks.  But the way you ran them is fine, as well.
