Mozilla, pidgin, gnome-terminal, emacs with GTK. All of them I occasionally use across an ssh tunnel and it's typically quite bad. It's good across a LAN with latency in the few ms range, but gets bad very quickly as latency increases - keypresses and redraws are noticably sluggish. xterm and emacs with Xt/Motif are all much better, even across links with larger latency. I seem to recall reading, years ago, a post or paper discussing network performance issues in GTK and Qt, and pinning the issue on too many round-trips. Xt/Motif were nicer in this sense, and hence their higher performance. But none of that has much of anything to do with fonts. -- Ross Vandegrift [email protected] "If the fight gets hot, the songs get hotter.
