During bootup, CPU utilization was somewhat higher.Yeah, that's what I can see here: fill_prefetch_030, fill_prefetch_030_ntx are using most of the CPU (about 70 %).
Unfortunatly, it's impossible on MacOsX.
I can't see any SDL function in the profiler, nothing, so SDL is now for negligeable part in performances. BUT i found something insteresting: the second Thread at 50% is not Hatari, but an Apple thread between Hatari Audio part and MacOsX, called com.apple.audio.IOTHreadClient. This thread use 50% of CPU, even if there is no sound playing.
In any other mode (ST/TT/...), this thread use less than 1% of CPU...
