I max out at 36 messages/sec when writing. (Yes, we use transactions, and we know it's not optimal, but we're valuing high reliability over speed. Our clients and/or servers could go away at any moment, so things like Publisher-acknowledge are nice, but take away from the fundamental disaster hardness.)</div><div><br></div><div>Anyhow, we're running on Ubuntu 10.04 with 2.71 and the default Erlang install. This gives us R13B03 as the Erlang version.</div><div><br></div><div>Question: Does anybody (and particularly the RabbitMQ folks) have any input on what sort of perf improvements we might get by switching to a newer Erlang Version?</div><div><br></div><div>Obviously every situation is different, but before going down this road, I'd like an idea of the order of magnitude of message rate improvements that people have seen. That is, are they closer to 5%, 50% or 500%? (500% is obviously a fantasy, but you get the idea.)</div><div><br></div><div>Thanks,</div><div><br></div><div>Matt</div><div><br></div><div><br></div><div><br></div></body></html>
