New description:
We need to do the following experiments to understand more about the
performance of Tor under simulated DoS conditions:
- Get vanilla profile (for #30221)
- See effect of DoS on intro and guard (profile them or just monitor CPU
and logs)
- Investigate control port experiment (with STREAM events enabled and
trying to kill circs with CLOSECIRCUIT)
- wrt https://lists.torproject.org/pipermail/tor-
dev/2019-December/014097.html
- Investigate horizontal scaling with OB
- See how load changes when scaled to 2/4/8 instances, extrapolate
onwards.
- Investigate size of replay cache (#26294)
- Investigate capacity of reestablish intro circuit (#26294)
- Compare intro/rend profiles (value of prop255 / #17254)
- Investigate pinned paths with HSLayer2Node HSLayer3Node
