Hello all ! o/
It seems I am running into a performance issue with my relay, and I am not able to troubleshoot it, so I hope someone could point out something obvious I am missing!
(for information, the relay is a 2vCPU, 2G RAM VM running on Scaleway)
From what I observe from the graphs, my maximal CPU usage ceils at ~60%, and the load ceils at 1 eventhough the TOR daemon is aware I have 2 cores available, and I set the NumCPUs configuration option accordingly)
First I tought that the network did not want to send me more traffic, but my graphs are way too regular to make this eventuality plausible, so I am pretty convinced that it is due to a lack of optimization on my side.
(link to my graphs for reference http://www.noelshack.com/2017-01-1483803911-constancesurvingt.png this is a 1 hour snapshot, but it has been this constant for at least one day)
My first hypothesis was that the daemon is running out of file descriptors, so I raised the limit that was in the defaults (doubled it actually, by editing /etc/init.d/tor like a pig, to test), but I did not observe any change in Grafana.
It is supposed to be caped at 20MBps, and 25MBps burst so I doubt the limitation I am observing is enforced by the node itself.
If anyone had any pointers I would be grateful!
Cheers!
