I have run it on a 2.6GHz with acceptable results. Two things were
critical: enabling Hyper-Threading, and getting the AGP setting right.
Depending on your motherboard, using nVidia's AGP is either a win or a HUGE
loose. Going to a nVidia FX-5700LE also helped.
Also note, setting "-march=pentium4" in settings.pro does *NOT* effect the
options used to compile the A/V decoding libraries. Those options end up in
config.mak after you do the ./configure. I have had good look using
something like "-O4 -march=pentium4" in the config.mak file.
Doug also discovered that "nice"ing X to a higher priority helps. X should
actually be at a higher priority than mythfrontend, which should be at a
higher priority than other general apps.
Is your machine a Backend/Frontend combo, or just a frontend? Splitting the
backend and frontend onto different machines also helped for me. The
backend can actually be a pretty lowely machine -- it just needs a good disk
system.
