Hello,

Thanks for running relays.

It desirable to have geographical diversity of course, but running two
in the same place to increase capacity doesn't do any harm. Just don't
forget to configure MyFamily in both torrcs so that the relays are
linked together as belonging to the same family.

This depends on a lot of things. If your network port can handle more
than 26MB, and the limit of 26 MB observed on the first relay comes from
CPU/RAM, the 26 MB will not be divided but increased. If the first relay
has underused CPU / RAM this means the 26 MB is a limitation that comes
from the network port speed, and in this case it will be obviously divided.

Yes, if the bandwidth grows. If the 26 MB is divided in two, it's easier
and better to run a single one of 26 MB (save space in descriptors
distributed network wide, have a single box to maintain and keep up to
date, etc.)
