Depends on the version. 0.1.2 only has decoding acceleration, 0.1.3 has encoding acceleration too... On a P-II 400, I get like 50% CPU usage on half-PAL encoding. libjpeg gave me 100% CPU usage (occasional framedrops because of too-slow-CPU). Which means jpegmmx is about two times as fast here. So on a P-III 800, I'd expect double performance, i.e. 25-30 fps full-PAL.
