[snip giant results URL.]
These results are a bit strange. For one, I noticed that the URL refers
to SunSpider 0.9, while the latest version is SunSpider 0.9.1. At least
one test in 0.9, regexp-dna, unfairly penalized Firefox because it used
an extension to the regexp replace API that only does something on Firefox.
So, you might want to run again with 0.9.1 and see how that looks. Last
time I ran SunSpider on a TM nightly (a week or 2 ago), we were 20%
slower than Chrome. It should already be even better than that.
On the x64 issue, we prioritized x86 performance, so making x64 fast is
going to take a little longer. Major improvements have been landing

I don't think that's true. I (and other JS devs) have blogged and
tweeted all year about what we're doing and what kind of progress we're
making. Bugzilla shows a list of all the performance problems that need
investigation or are being worked on.
