* Optimize AbstractByteBuf.getCharSequence() in US_ASCII case Motivation: Inspired by https://github.com/netty/netty/pull/8388, I noticed this simple optimization to avoid char[] allocation (also suggested in a TODO here). Modifications: Return an AsciiString from AbstractByteBuf.getCharSequence() if requested charset is US_ASCII or ISO_8859_1 (latter thanks to @Scottmitch's suggestion). Also tweak unit tests not to require Strings and include a new benchmark to demonstrate the speedup. Result: Speed-up of AbstractByteBuf.getCharSequence() in ascii and iso 8859/1 cases |
