Could you comment on the verisimilitude of the benchmark parameters? I would expect in Facebook's production environment the number of active sockets would be hundreds or thousands of times greater than 400.
You're right we see many more connections in production. We didn't have enough time to run exhaustive benchmarks for all the different possible combinations of active sockets, requests per connection, etc. As you might suspect, 400 was a sweet spot for our performance numbers at 1 core. Overall RPS didn't dip too much when increasing the number of connections. The table we included is just to give a rough idea of perf.
