Recompressing a 3min, 49sec 704x384 AVI with VirtualDubMod (fast recompress). No audio. Output written to the first partition of a RAID-0 volume to take hard drive speed out the equation as much as possible. YV12 -> YV12. Total time as displayed by VirtualDubMod.
Old E6750 dual core CPU, 3.2GHz. For Lagarith and MagicYUV there's two time and CPU usage figures. Without and with multi-threading enabled. CPU usage is a fairly rough average anyway.

Huffyuv (ffdshow variant), 16 seconds, CPU 62%, 990.8MB
Huffyuv (ffdshow variant, adaptive huffman tables enabled), 16 seconds, CPU 62%, 587.2MB

FFV1, 62 seconds, CPU 58%, 432.6MB

Lagarith, 18/15 seconds, CPU 60%/73%, 503MB

MagicYUV, 17/12 seconds, CPU 60%/83%, 586.8MB

For a hard drive speed reference..... copying the largest file (990.8MB) from the location of the source file to the same location as the output files took around 6 seconds.

And for fun:

Uncompressed YV12 (Avisynth script/Direct Stream Copy), 15 seconds, CPU 45%, 2.1GB
Uncompressed RGB, 30 seconds, CPU 45%, 4.3GB
