[tor-relays] Declining Relay Usage

[likogan]

My exit relay has seen steadily decreasing traffic from 8MBps to 6MBps 
over the span of three weeks. It averages a load of ~50% CPU usage and 
~65% RAM usage. It's rated network capacity is 17Mbps on a 10GB link. 
Why would traffic decrease if I have plenty of spare resources? Are 
there ways I can configure my server to boost traffic?
