I agree Akka has way more mindshare than Retlang/Jetlang. DRW seem to be happy to throw it over the wall but not promote their stuff. I'm curious about the perf figures. Mike was reporting 2.3m msg/s in 2007 and it's seen a number of perf improvements since then (as has hardware :)). Admittedly, I'm sure it could be optimised further since it just uses classic locks.

And this is a single datapoint, I know, but it's _ridiculously_ stable in my experience.

Literally, I've been telling people to just use Retlang since 2007. So many people still just fire up the threads and locks...
