My system specs:
Dual P4 Xeon 3.06ghz
2 gigs RAM

Using multi-encoder, getting some *very* slow encode times:
15 files (ripped to Hard Disk as .wav) encoding to:
WMA: 20, 32, 128 and 192 kb (wma 9.1 non-pro) and 256 mp3 (LAME)

25 minutes

Wow.
499 files, same setup: 15 hours. (11 hours remaining!)

Is there something I should be looking for to speed this up? 15 files in 25 minutes is a bit.. excessive.

EDIT: More details: only utilizing 7% of the processor, via task manager (yeah, I know it's inaccurate, but my system is still very very snappy, so... )
Dialog box shows 2.1x Encoding Speed, and unlike a single encode, there are no 2 cpu's listed (I did just pause it and crank out 499 256kbit mp3 files fairly quickly, and it shows both processors in use for a single encoder).

WMA is a funny one, microsoft have backend multi-thread code, so out of all encoders it is the one most likely not to be happy with multi-encoder. First check you have the latest wma encoder as there was a memory leak with an older one.

Try also for a test using 6 different mp3 encodes.
