Sure, it's interesting to compare. On my 64 bit machine (Selmer):

I'm less impressed with the unbalanced multiplication than I was 10 minutes ago. :-( Clearly their division code has improved and our cube root code still sucks and our gcd and xgcd still needs optimising (that one file I keep carrying on about).
