Hey!

I had the same problem and just stopping verynice changed the whole situation. You should be able to put in Tuxpaint and Tuxtype as an exception in verynice or just switch verynice off to see if it fixes the problem. 

Verynice is there to stop applications from running away and grabbing to much cpu. 

Try doing this as root and see if it helps:

/etc/init.d/verynice.init stop

So even with the the gbit switch, it is still too slow to use? The 
teachers at my school are getting really upset about it and saying that 
it's a showstopper, if those apps don't run smoothly they're going to 
cancel the whole thing. If I buy gbit switches and it's still too slow, 
they're going to be even more ticked.
