SIMDjson 5.0 Released: Still Making JSON Parsing Even Faster

SIMDjson is the open-source, high performance JSON parser that surprisingly began making use of AVX-512 to deliver big performance gains years ago. SIMDjson has continued further refining itself to deliver even greater speeds and out today is SIMDjson 5.0.

SIMDjson 5.0 promotes its static reflection support to being an officially supported feature, better handling of big integer numbers, and a lot of smaller features -- including performance optimizations.

The SIMDjson 5.0 release announcement on GitHub goes over the changes as well as some benchmarks comparing SIMDjson 4.0 and SIMDjson 5.0.

I ran some benchmarks on my side of SIMDjson 5.0 compared to the prior SIMDjson 4.6.4 release and indeed seeing some decent gains on top of all the other SIMDjson optimizations of recent years:






There are more SIMDjson CPU benchmarks for those interested. Crazy to see how fast SIMDjson has pushed JSON parsing performance.
