Hello,

Don't cap the speed if you have bandwidth limits. The better way to do
it is using AccountingMax in torrc. Just let it run at its full speed
less of the time and Tor will enter in hibernation once it has no
bandwidth left.

Example:
remove RelayBandwidthRate, RelayBandwidthBurst and
TokenBucketRefiillInterval or any other strange and unnecessary
settings you might have for bandwidth limiting. Add the following:

AccountingMax 96 TBytes
AccountingStart month 1 00:00

Search for 'accounting' here:

Thanks for running an exit! More to come ;)
