-------------------------+-------------------------------------------------
 We need to do the following experiments to understand more about the
 performance of Tor under simulated DoS conditions:

 - Get vanilla profile (for #30221)
   - Need to get more understanding about CPU vs network saturation
 - 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
