welcome to Linux.

network equipment, you will need to segment your terminals' LAN for speed.

Segmenting the terminals' LAN into seperate subnets will cause you a lot
of work, and probably pain too..

The easiest way is to cable the terminals direct to a switch, and 10MBit
here will be fine.  Remember, a switch is not a hub.  However, you will
need to cable the switch to the LTSP server using 100MBit (or faster)
networking hardware.  I don't know how much you will spend if you use a
1GBit link server<-->switch, but I would suggest that you price this
combination, consider it an investment in your Labs' future, and then
decide what to buy.

I haven't done anything like that, but it sounds like the difficult way
to me.

hope that helps.
