Comment (by robgjansen):
My sanity-check experiments finished. In one experiment I ran 'vanilla'
Tor with stable release 0.2.5.10, and for the other experiment I used the
`cmux_refactor_configurable_threshold ` branch and the following settings:
{{{
SchedulerLowWaterMark 100MB
SchedulerHighWaterMark 101MB
SchedulerMaxFlushCells 1000
}}}
[https://trac.torproject.org/projects/tor/attachment/ticket/12889/cmux-
sanity.shadowtor.pdf.xz The results] confirm that the new branch with the
above settings results in performance very similar to vanilla Tor.
The network model included 400 relays and 1200 clients downloading files
of the various sizes shown in the graphs. Keep in mind that in this
smaller network, there will be some amount of variance in these
experiments due to the different Tor builds being run. I could run this on
an updated full ShadowTor network of 6000 relays when I finish producing
one, but I don't think these results warrant doing so.
I believe that merging this branch and using settings similar to those
above would not destroy performance. I'll next show some results of
testing with different parameters.
