Subject [jira] [Commented] (CASSANDRA-8457) nio MessagingService
Date Fri, 12 Dec 2014 15:10:13 GMT


Ryan McGuire commented on CASSANDRA-8457:

I've just tried to bring up a 25 node EC2 cluster on cstar_perf, and it did so without hiccup.
We have an automatic tool for installing cstar_perf.tool on EC2, it's still lacking integration
with the frontend though (meaning you can run tests against it, with the frontend, if we attatch
the cluster. You just can't create the cluster from the frontend, yet.)

> Thread-per-peer (actually two each incoming and outbound) is a big contributor to context
switching, especially for larger clusters.  Let's look at switching to nio, possibly via Netty.
