I've been wondering where you've been lately Roger :p

Releasing Helios 2.0 today, which is a big improvement over the previous version.

Stress test results across 350 connections (ramped up over a 3-5 minutes, each connection doing 250 msg / s): https://gist.github.com/Aaronontheweb/ab3ae953239de81752c357...

Also includes 1 million message throughput tests for duplex and inbound-only receive. On the inbound side we peak out at about 250k / s on a single connection. Write side is slower at the moment due to lack of batching on flush, but that'll be fixed.
