Subject [jira] [Commented] (CASSANDRA-6861) Optimise our Netty 4 integration
Date Mon, 05 May 2014 23:58:19 GMT

Ryan McGuire commented on CASSANDRA-6861:
-----------------------------------------

The read drop was a fluke, here's trial 2: http://riptano.github.io/cassandra_performance/graph_v3/graph.html?stats=stats.6861.2.json

This was a comparison of f0575f153b8 from 2.1 HEAD and your branch' 784db2fde2.

I can re-run this against your rebase 4b6b819a53.

> Now we've upgraded to Netty 4, we're generating a lot of garbage that could be avoided,
so we should probably stop that. Should be reasonably easy to hook into Netty's pooled buffers,
returning them to the pool once a given message is completed.
