Subject [jira] [Commented] (CASSANDRA-6861) Optimise our Netty 4 integration
Date Tue, 06 May 2014 21:02:19 GMT


T Jake Luciani commented on CASSANDRA-6861:

Pushed changes for 1 and 2 plus added exception checks to free resources.

For 3, calling Unpooled.buffer() is a on heap buffer call. I don't see them changing that.

bq. What about the "SSL - Don’t use JDKs SSLEngine if performance matters" part of the slides?
Are we going to handle that as part of this ticket?

I don't know about you but I prefer to stick with the JDK here for security reasons.

> 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.
