[tor-relays] How to reduce tor CPU load on a single bridge?

I'm not using nyx. I'm just looking at the bandwidth on the network
interface.

We're trying to avoid rotating keys at all. If the read-only files do not work, we'll instead probably periodically rewrite the state file to push the rotation into the future.

I don't know if it's wrong, exactly. It's reporting something different than what ExtORPort is providing. The proximate connections to tor are indeed all IPv4.

Sure, there are plenty of ways to increase resources of the bridge, but I feel that's a different topic.

Thanks for your comments.
