Description

The LineBasedFrameDecoder is optimized version of DelimiterBasedFrameDecoder which provide some good performance gain. The DelimiterBasedFrameDecoder already automatically use LineBasedFrameDecoder if we use DelimiterBasedFrameDecoder (but not subclass) and with CRLF/LF as delimiter. However in SMTP and IMAP server we have to subclass it, therefore we should directly extend LineBasedFrameDecoder for the performance gain.
