 The fact is. Not all processors are equal with 64 bits mode.

 A core 2 duo, running a 64 bits kernel *is* slower than a 32 bits one.
Not so long ago, got a few reports that a 0.25 version of myth wasn't
playing a file well, when 0.24 was just fine. This was on a mac.
Turned out, by default I had made the app use 64 bits; because hey, 64 is
at least twice better than 32 :)

Turned out, that's true on i3,i5 and i7, but not so on core 2 duo.
