Dunno how many folks have machines with the newer toys in them, but I just 
ran perlbench against 5.6.0. It turns out that if you specify an 
/ARCH=HOST, and compile on an EV6 system, perl gets an overall boost of 
about 5% over a plain build. Some of the tests show a more significant 
boost (the string/base64 test got a 40% boost over a plain compile, and 
string/tr jumped 70%), generally those that deal with strings, which makes 
sense given the extra instructions in the EV5+ processors.

The sad thing is that, even with the extra goodies, 5.6.0 was only 15% 
faster than 5.004_04, and that was with 5.6.0 racking up a numeric sort 
result 4x that of 5.004_04. (Plus 5.6.0 was built with the Dec C 6.2, while 
5.004_04 was built with, I think, Dec C 5.5...)

I don't think we're quite pulling ahead here, but I don't know exactly 
where 5.6.0's losing it's performance.
