ASF GitHub Bot commented on JAMES-2310: --------------------------------------- Github user chikei commented on the issue: https://github.com/apache/james-project/pull/98 As the DelimiterBasedFrameDecoder from netty (which LineDelimiterBasedChannelHandlerFactory directly construct) will automatically use line decoder if we use it directly and with CRLF/LF as delimiter, so only IMAP and SMTP will actually gain some performance from this changes. Therefore I only make change to SwitchableDelimiterBasedFrameDecoder/AllButStartTlsDelimiterChannelHandler in new commit, if you prefer also make LineDelimiterBasedChannelHandlerFactory explicitly use line frame decoder I'll make additional changes. > Use LineBasedFrameDecoder instead of DelimiterBasedFrameDecoder > --------------------------------------------------------------- > > Key: JAMES-2310 > URL: https://issues.apache.org/jira/browse/JAMES-2310 > Project: James Server > Issue Type: Improvement > Components: IMAPServer, SMTPServer > Affects Versions: 3.0.1 > Reporter: TzeKai Lee > Priority: Major > > The LineBasedFrameDecoder is optimized version of DelimiterBasedFrameDecoder > which provide some good performance gain.
