libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. ...

...If you are doing a lot of log processing or number crunching, but stuck with JSON, you definitely need to consider dsl-json or Jsoniter to save the encoding/decoding cost. Is protobuf 5x faster than JSON?. Jsoniter Golang version could be more than 6x times faster than standard lib (encoding/json). And the number is acheived with runtime reflection instead of go generate.
