Keep testing, run some benchmarks please. I im interested about improvements from interpreted JS from 3.6 to interpreted JS in 4.0 :) Any possibility to merge this patches upstream? As of JIT, it would be quite hard and will took some time. JIT in 4.0 is much more improved, but AFAIK Firefox works already on next JIT, so this is very moving target. BTW do you know if internally this JIT is simpler or more complex than previous one? And how well it separate target depended code genration from rest of the engine? They probably support now i386, amd64, ppc and arm right? Do they have plans for other architectures? -- Witold Baryluk
