<p>Hi Roger.</p>
<p>My concern is not really bandwidth. I started the relay with 2MB/s. I can always push some more and I'm gradually moving the bar up to the highest possible. I'm concerned because the VPS does have limited resources in terms of CPU and RAM. As long as the relay stays stable I have no problems sharing some more. I just don't want to crash the VPS by exhausting its resources and making the relay a tort. That's not healthy for the network hence my concerns. </p>
<p>Yeah, I'm using arm to measure it and I think I've over-reacted because irrespective the spikes it is reporting 3.1Mb/s as average.</p>
<p>I have now raised the limit to up to 10MB/s let's see how it handles it.</p>
<p>Thanks for your input. I appreciate it.</p>
<p> </p>

<pre>Yes, it can oscillate for some relays, if some directory authorities
think the relay deserves the Guard flag and others don't.
It's not great, and we should probably fix the design sometime, but
it's also not so bad.</pre>

<pre>Are you sure? What tool are you using to measure this? If it's arm, be
ware that arm by default tells you throughput in bits, and Tor measures
things by bytes.</pre>
<blockquote type="cite" style="padding-left:5px; border-left:#1010ff 2px solid; margin-left:5px">Most of the time, my relay pushes between 3-7MB/s constantly and that's fine. But there are occasions in which I see it spike and send out as much as 12MB/s when I have set a limit of @6MB/s.</blockquote>
<pre>Based on the graphs above, you're using maybe .5MB/s each way on
average. That reinforces my guess about the bits/bytes confusion.</pre>

Thanks for running a relay!
