[tor-dev] estimating traffic/bandwidth needed to run a Tor node

Your email is confusing. To host a Hidden Service you do not need to be
a Tor node - we call them relays in the common terminology.
So, a relay relays traffic for Tor clients. This will consume as much as
you give. You can throttle the relay bandwidth rate / burst or limit the
traffic consumed by accounting per day/week/month, etc. After the speed
and traffic limits, next limits are CPU, RAM and so on.
There is no sense in being a relay just to host a hidden service. In
fact we do not recommend this, it's better to run the hidden service and
relay service in two separate Tor processes if hosted on the same device.
To only host a hidden service you can be a normal Tor client. This will
not consume any traffic or relay traffic for other clients, but it will
consume as follows:
a) all traffic generated by that hidden service. This can be only
estimated by you, since it can be 0, it can be 1 MB per week it can be
100 MB per day, etc.
b) consensus data and microdescriptors for relays in the network. I
don't have exact numbers for how much is this but count few MBs at every
2 hours just to be sure.
