Hi DaFinn,
the fastest client is still the windows one running in wine under linux.
I'm pretty sure the guys that use linux use setidriver also. Someone
that runs linux will be around shortly to confirm or deny this .

from what I heard the GUI is 30 to 50% slower, and I don't know if there's one for Linux.
Sorry I can't help more,
just hang on a bit and you'll get a defenite answer from one the Seti gurus.
Paf
edit: Gary you beat to it , I still am a bit slow typing with one hand,LOL
