TuxType is known to use 73Mb/sec *per client* at 1024x768 at 16-bit
color. And your server's on 100BaseTX? No wonder you're having
slowness issues! :-)
Yes, go Gig-E on your server. After you've done that, then do a Gig-E
link between the main lab switch and the second lab switch, or the folks
in the second lab will have a problem (73Mb * 8 terminals = way more
than 100Mb). Look, it's either that or spend tons more money on Windows
boxes, with virus/worm issues, BSA audit threats, etc.; you're still
saving major, major cash here, dude.
