Have a new exit running in an excellent network on a very fast server with AES-NI. Server plan is limited to100TB so have set a limit slightly above this (18000000 bytes/sec) thinking that bandwidth would run 80-90% of the maximum and average to just below the plan limit. After three days the assigned bandwidth for the relay is going up instead of moderating--looks like the measurement system has a problem in this case. Just dropped the limit to 16500000 to stay below 100TB with maximum load.
What can be done to extract proper rating from measurement system? . . . Can the rating system be fixed?
