Re: [tor-relays] Fast Exit Node Operators - ISP in US

If the only limit is consumed monthly traffic, and not the bandwidth
your relays consumes daily (e.g. you use your VPS only for Tor) it is
not recommended  to use RelayBandwidthRate. Better use AccountingMax,
and your relay will work at full speed until it hits the accounting
limit, then go into hibernation. It will wake up at a random time in
the next accounting period.

As the Tor manual says, it's better to have a fast relay available
some of the time instead of having a slow relay available all the time.

Just use AccountingMax and do not forget there are other factors as
well which count in the speed of a relay, such as CPU, RAM, network -
a VPS (share resources machine) is unlikely to achieve maximum
resources usage. Give it a try with AccountingMax (so you are sure it
won't bypass the limit set by your provider and you don't have to pay
extra) and see what what speed it reaches.
