Hi!
I'm working on a model to estimate the number of connections an OR has open as a function of the OR's bandwidth. I could really use some help confirming that my model is reasonable. Would any relay operators be willing to share the results of some variant of netstat | wc -l and the bandwidth of the relay?
Thanks,
Tim
Sure, what info do you need?

Hi Tim,
Sure. If you need more numbers from our other servers let me know ( https://www.torservers.net/services.html#servers ). Looking forward to your results!

Exit server with maxed-out 10Mbit connection (1.1MB/sec):
# lsof -ni | grep _tor | wc -l 546
Relay server rate-limited to 150KB/sec:
# lsof -ni | grep _tor | wc -l 132
Regarding the relay server: torstatus.blutmagie.de reports Observed bandwidth of 51KB/sec while Vidalia reports 172KB/sec.
Neither server is CPU- or memory-constrained, and the relay server is not bandwidth constrained.
With all that said, I don't expect success in your endeavor. In my experience, traffic on relays is really, really erratic. Look at how the utilization bounces on a Stable server:

Good luck modeling (and end-users estimating the use of their Internet connections) this kind of variation in network utilization.
