For proper DSP emulation you typically need ~2Ghz machine or better
(And the more accurate the emulation is made, the slower it will be).

If you're running programs that don't need DSP, disable DSP emulation
(toggling that needs emulated system reboot as DSP isn't hot-swappable
on real hardware).  If program uses DSP just for background music,
but doesn't normally work without DSP, you might e.g. try disabling
music and play the music from mp3's outside of Hatari.  :-)

Yes, GemBench does it's measurements inside the emulation
(as it's an Atari program :-)).

Sorry, I didn't notice that the mail was from BerliOS times
