It's certainly an issue with rendering glyphs, for the reason you state. Sun Ray utilizes a glyph cache for bandwidth compression, but this sort or anti-aliasing ensures zero cache hits :-(. There are also performance issues when applications don't use tiling for scrolling. xterm and dtterm did, but gnome-terminal does not. -Bob
