>Finally, the connections per second rate reaches 99k, with network latency and available CPU resources contributing to the next bottleneck.

Can someone educate me on what they might talking about here ? CPU is ~45% in their final graph. I don't know what network latency means in this context though. Roundtrip for a TCP handshake ? That seems unlikely.

The CPU graph peaks near 97% (teal line) at the time when connections-per-second are highest. Are you looking at the red? That's the version without the two patches.

oh yeah, you're right. I reversed the two in my head somehow.

It means CPU is not saturated, so it is not the bottleneck, which means it is likely not enough Erlang processes have been started.
