Much appreciated! Oddly enough the standard tools don't seem to show the 
rPi server struggling much at all  tor seems to take 7-20% of cpu-- 
running 'arm' seems to add an equal amount of load as the tor daemon 
itself. I'm actually thinking that running 'arm' constantly in a 
terminal status window may be bogging down the rPi but I'd like to 
figure out some logging/debug magic to 'prove' to myself that I've got 
an underwhelming box.

If I can trace performance problems to the rPi I'll happily swap in 
another dedicated box as a replacement.
