Avery Ching commented on GIRAPH-840: ------------------------------------ Thanks Eugene! > Upgrade to netty 4 > ------------------ > > Key: GIRAPH-840 > URL: https://issues.apache.org/jira/browse/GIRAPH-840 > Project: Giraph > Issue Type: Improvement > Reporter: Pavan Kumar > Assignee: Pavan Kumar > > Off late netty 4 has earned so much praise in the community. For example, > https://blog.twitter.com/2013/netty-4-at-twitter-reduced-gc-overhead > A switch to netty 4 enables a significant reduction in gc pressure and also > huge performance gains. I started working on this last Sunday and have a > patch that shows performance gains on the order of 15-25% (total execution > time) for some applications at Facebook. However, I only tested it with > hadoop_facebook. So there might be issues with SASL path. > I will release the patch today and want to open up a discussion if anyone is > using the secure feature anymore. If not we can just deprecate it. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
