Fairly solid gains for the most part, although the regex performance regressions are curious.

Amazing. Am loving following this language and its take o. structural typing.

Question: Is Intel so dominant that optimization of AMD chips isn't a high priority? Not complaining.

I believe Intel platforms is supposed to be understood as x86 chips.

If you look at the samples they specify /AMD64 for 64 bit and /386 for 32bit.

True. I would expect IA-64 chips to benchmark differently from AMD's amd64 chips, though. Would be interesting to see them (the percentage changes for each arch, relative to 1.1) side-by-side.

Err...IA-64 is the Itanium instruction set. You mean EM64T, no?

Wikipedia says "Intel 64" is the new official name, but yeah, IA-64 looks wrong. Sorry. IA-64 feels like it should be the 64-bit-ified IA-32, but no...

Hard problems in CS: Naming things.

You're actually right...IA-64 was suppose to be the 64-bit Intel instruction set, right up until AMD dropped the AMD64 bomb and the market went "backward compatible...got to get me some of that" and Intel went scrambling for Plan B.
