We've replaced the 1.15v encoder for Windows with a faster compile that's been tested with many tracks and it proved to produce identical files to the older mppenc. Speed tests show between 5% and 14% of speedup on a variety of CPUs. Tests were carried out on:

Celeron 333
Pentium M (Dothan)
Pentium 4 (Northwood)
Xeon

Athlon
Thunderbird
Athlon XP
Athlon 64 (Clawhammer, Newcastle, Venice)

What changed? ICL? Visual Studio with processor pack? Different compiler switches?

I'll be able to take advantage of this as soon as Amazon sends me the CDs they've delayed for three months.
