Enable TCP_NODELAY by default for IPC -------------------------------------
Key: HADOOP-8069 URL: https://issues.apache.org/jira/browse/HADOOP-8069 Project: Hadoop Common Issue Type: Improvement Components: ipc Affects Versions: 0.23.0 Reporter: Todd Lipcon Assignee: Todd Lipcon I think we should switch the default for the IPC client and server NODELAY options to true. As wikipedia says: {quote} In general, since Nagle's algorithm is only a defense against careless applications, it will not benefit a carefully written application that takes proper care of buffering; the algorithm has either no effect, or negative effect on the application. {quote} Since our IPC layer is well contained and does its own buffering, we shouldn't be careless. -- This message is automatically generated by JIRA.
