before you've run anything but stats?  that's interesting.
it could be a problem with usb, but maybe it's just a plain old
interrupt problem.  if you have *nomp=1 in you plan9.ini,
you could try removing it.  that's a bit of a wild guess, but
i do not see this behavior on my terminal with a usb mouse.
and that machine has an intel atom processor, which should
offer just the same performance as your t23.
