Hello all,
I recently acquired a server with "unlimited" (not unmetered) bandwidth on a non-Hetzner/OVH/Scaleway network, but the pipe is just 100mbit (and will be saturated at some points by personal traffic bursts). That being said, I expect the 100mbit pipe to be idle 90% of the time, so it doesn't seem ideal to just set a low BandwidthRate.
The documentation [1] for relay bandwidth shaping options points to a script to de-prioritize Tor traffic to ensure that personal traffic takes precedence.
However, the script no longer exists within Tor source code. [2] Is this script now deprecated? If not, where can I find it? If so, what alternative methods might exist to de-prioritize Tor traffic during bursts from personal traffic pipes on Linux or BSD systems?
Thanks all!

Hi
The Tor service might not be able to detect if your private usage is high or not. I would suggest the solution at OS level. Typically congestion balances according a fairness modell which stands against your intention.
what alternative methods might exist to de-prioritize Tor traffic during bursts from personal traffic pipes on Linux or BSD systems?
On BSD you could investigate in pf-altq and define customized queues. But that will impact the bandwidth measurements and the consensus for your relay.

It looks like yes, we removed it: https://gitlab.torproject.org/tpo/core/tor/-/issues/29434 https://lists.torproject.org/pipermail/tor-relays/2019-February/016995.html
So it definitely counts as deprecated, in the sense that nobody maintained it for a long time and then somebody deleted it. :)
But that said, I bet it would still work, or at the very least, it would be a good set of hints for how to write a new one. If you do write an updated one, please share it here.
You can find a copy in earlier git branches, e.g.: https://gitweb.torproject.org/tor.git/plain/contrib/operator-tools/linux-tor...
Hope this helps! --Roger
