>[warn] Your computer is too slow. . .

Raspberries are cute but seriously
underpowered for crypto-intensive
applications such as Tor.  You can
(any/all of)

1) ignore the warnings

2) restart the relay to send-off
any hidden services that might
be causing the overload

3) buy a dirt-cheap used laptop
or mini-tower on eBay to run
the relay

4) buy a Beagle Board if you enjoy
fiddling with miniature computers
--much more powerful device

The configured limit is reasonable
for the device.
