  "message": "Pre-allocate storage in http2::HuffmanEncode().\n\nAlso, do not call http2::HuffmanEncode() in\nQpackInstructionEncoder::DoStartString() if it does not result in size savings.\n\nNote that performance gets worse for short strings, presumably because\nstd::string::reserve() for small values is a no-op due to small string\noptimization.  However, I plan to modify http2::HuffmanEncode() not to clear the\noutput string and modify QpackInstructionEncoder to avoid copying, which should\nresult in a performance improvement overall.\n\nAlso I\u0027ll add a slightly faster implementation in the next CL, so this is really\nonly to change the API to make tests simpler.\n\nPiperOrigin-RevId: 334909897\nChange-Id: Idd7414c0dcaa56fc62d0822ec06250d480d2972c\n",
