FWIW, the example config file ("torrc.sample") includes these lines:

## Define these to limit how much relayed traffic you will allow. Your
## own traffic is still unthrottled. Note that RelayBandwidthRate must
## be at least 20 KB.
#RelayBandwidthRate 100 KB  # Throttle traffic to 100KB/s (800Kbps)
#RelayBandwidthBurst 200 KB # But allow bursts up to 200KB/s (1600Kbps)
