8mb flash, 32mb ram is probably the lower bound for a useful Tor
client / hs host device. remember to omit geoip from the tor pkg :)

and only as bridge if not already running hidden svc,
and not more than a few distinct onions per device.
a longer hidden service performance discussion spans:
"Hidden Services are in a peculiar situation. While they see a loyal
fan-base, there are no dedicated Tor developers to take care of them."
"[tor-dev] Hidden Service Scaling"
"[tor-talk] Hidden Services - how to implement something like Round Robin DNS?"
"Rumors that hidden services have trouble scaling to 100 concurrent connections"
Increase NumEntryGuards to 3 or 5

you'll want to squeeze the best reduction across toolchain (uClibc
opts) and application (for example, ConstrainedSockets opts) even
system tuning (ulimits, /proc). some of this is on the Torouter page:
https://trac.torproject.org/projects/tor/wiki/doc/Torouter the rest on
the list archives...
in general terms, there is not a good set of measurements for Tor
client/hs serv performance. most performance attention focuses on
relays or crypto primitives.
i'd like to run common Tor client/hs-serv benchmarks across a variety
of platforms. in particular the i.MX53 and i.MX6 line as step up
compute wise from these units. e.g.
http://www.inversepath.com/usbarmory.html for a nice i.MX53 device.
