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?

MSVC 8.


P.S., speeds with --quality 5 on a P4 2.6C:

1.15v old: 18.7x

1.15v new: 20.4x

9% speed increase

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