Norman Maurer d7d8503f5c Add a line-based frame decoder with good performance. ... Using DelimiterBasedFrameDecoder with Delimiters.lineDelimiter() has quadratic performance in the size of the input buffer. Needless to say, the performance degrades pretty quickly as the size of the buffer increases. Larger MTUs or loopback connections can make it so bad that it appears that the code is "busy waiting", when in fact it's spending almost 100% of the CPU time in DelimiterBasedFrameDecoder.indexOf(). Add a new LineBasedFrameDecoder that decodes line-delimited frames in O(n) instead of DelimiterBasedFrameDecoder's O(n^2) implementation. In OpenTSDB's telnet-style protocol decoder this resulted in throughput increases of an order of magnitude. Change DelimiterBasedFrameDecoder to automatically detect when the frames are delimited by line endings, and automatically switch to using LineBasedFrameDecoder under the hood. This means that all Netty applications out there that using the combo DelimiterBasedFrameDecoder with Delimiters.lineDelimiter() will automatically benefit from the better performance of LineBasedFrameDecoder, without requiring a code change.		2012-11-25 13:36:55 +01:00
