found legacy trac documentation for you
this page doesn't seem to have been migrated to this wiki, and probably should be examined:
https://gitlab.torproject.org/legacy/trac/-/wikis/org/operations/services/onionperf
i had originally imported into the TPA wiki, as i did with a few such orphaned wiki pages such as this one, until I found this wiki.
it might be worth merging all this in the team wiki here instead:
https://gitlab.torproject.org/tpo/metrics/team/-/wikis/home
... or at least cross-ref those.
