[K12OSN] tuxpaint and others running slow

[gKw-X]

Hey all,

The teachers were playing with the system the other day and realized 
that tuxpaint/tuxtype and other such programs that paint their own 
interfaces (ie. most of the kids programs), run incredibly slow over the 
network... To the point that they're unuseable. Any idea what the 
bottleneck is here? Is my server too slow, or is the 100meg switch 
uplink choking things? The server has a gigabit ethernet but the switch 
only takes in 100megs... The student machines range from early pentiums 
to p2 400s, all have the same problem.

Thanks!
Matt
