Comment (by pastly):
Also FWIW, I'm currently running this change in small Shadow networks as
I'm testing other things. I'm measuring kernel queue time, tor queue time,
network throughput, and time to download. By these four metrics, this
change doesn't hurt a relay in a small network. It also doesn't really
seem to help.
I started a large Shadow simulation a couple days ago, but it died
sometime last night :(. I've started it again. I will report back when it
has finished. I suspect the small network was too small for the difference
to be noticeable. Namely
- not enough channels from one relay to ~all others
- not enough circuits per channel
The large network has 500 relays and 7500 clients compared to the small's
11 and 12 respectively.
