## Fluent Bit and SIMD for JSON encoding

Starting in Fluent Bit v3.2, performance improvements have been introduced for JSON encoding. Plugins that convert logs from the Fluent Bit internal binary representation
to JSON can now do so up to 30% faster using Single Instruction, Multiple Data (SIMD) optimizations.
The release of Fluent Bit v4.1.0 introduced new performance improvements for JSON encoding using Single Instruction, Multiple Data (SIMD). Plugins that convert logs from the Fluent Bit internal binary representation
to JSON can now do so 2.5 times (read) faster. Powered by the [`yyjson` project](https://github.com/ibireme/yyjson).

Look for the `simd` entry, which will indicate the SIMD support type, such as `SSE2`, `NEON`, or `none`.

If your Fluent Bit binary wasn't built with SIMD enabled and you are using a supported platform, you can build Fluent Bit from source using the CMake option `-DFLB_SIMD=On`.

## Run input plugins in threaded mode

By default, most of input plugins runs in the same system thread than the main event loop, however by configuration you can instruct them to run in a separate thread which will allow you to take advantage of other CPU cores in your system.
