Subject [jira] [Commented] (CASSANDRA-8457) nio MessagingService
Date Wed, 17 Dec 2014 14:22:13 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8457?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14249884#comment-14249884

T Jake Luciani commented on CASSANDRA-8457:
-------------------------------------------

This test doesn't deal with the signaling cost within the node.  We have a thread blocking
on the readExecutors completing.  This does tie into CASSANDRA-5239 but part of the goal here
is to push the callbacks to the edge without relying on explicit block/signalling calls.

> 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.
