There are settings you can add to your torrc to limit both the speed of your bandwidth and total amount of data sent per period, have a look at this two links:

http://rzuwtpc4wb3xdzrj3yeajsvm3fkq4vbeubm2tdxaqruzzzgs5dwemlad.onion/relay-operators/limit-total-bandwidth/

For example if i want my relay to use 3MB/s average with a burst of 6, and no more than 1 TB in a month one could put this in their torrc,

RelayBandwidthRate 3 MB # Throttle traffic to 3MB/s (24Bbps)

RelayBandwidthBurst 6 MB # But allow bursts up to 6MB/s (48Mbps)

AccountingMax 1TB

AccountingStart month 1 12:00

Hopefully this helps

Hi
Is there a tutorial on how to limit a relay's throughput?? There has to be!
I did a search and came up empty. I'm trying to avoid shutting down my
relay's due to financial burden Any help would be appreciated.
Thank you!
