Not really comparing like-for-like, but with 2010 Macbook Pro (2.66 Ghz Core i7, 8Gb) and ffmpeg HEAD, transcoding a 3-hour program gives these numbers:
real 5m7.197s user 4m56.078s sys 0m6.127s Just for kicks, in a 32-bit 1-CPU Ubuntu 10.10 VM (via VMWare Fusion) on the same machine I get this for the same file: real 5m48.907s user 5m30.741s sys 0m11.337s ffmpeg saturated one of the CPU cores in both cases, so the difference is more-or-less from the VM overhead. That's OK for my purposes, but it's not hard to see how it could be pokey on older hardware.
