Most likely, the interactive performance is a result of the RX
packet coelescing, with a timer set to too long an interval.  In
general, it's probably an easy adjustment to make.

I notice that he also says he didn't know what to add into some
of the timer and media routines, so that could be part of the
issue as well (e.g. if it's getting wedged and having to unwedge
itself).

BTW: As a rule of thumb, if you don't know what to put in a timer
or media routine, put a printf() there.  It will likely annoy
someone into fixing it.  8-).
