svn commit: r1650639 -
/tomcat/trunk/java/org/apache/tomcat/util/net/Nio2Endpoint.java
Author: markt
Date: Fri Jan 9 20:08:10 2015
New Revision: 1650639
URL: http://svn.apache.org/r1650639
Log:
Code review looking for possible causes of performance drop in NIO2.
The completion handler will clear the socketWriteBuffer so no need to do it again in flush. This restores a few % of performance.
