Is cpp a good language for reading and writing large quantities of JSON files as quickly as possible?

• simdjson

  65 18,538 9.2 C++

  Parsing gigabytes of JSON per second : used by Facebook/Meta Velox, the Node.js runtime, ClickHouse, WatermelonDB, Apache Doris, Milvus, StarRocks

  

For read speed there is a simdjson https://github.com/simdjson/simdjson I've not used this but the speed looks impressive.

• RapidJSON

  15 13,918 5.9 C++

  A fast JSON parser/generator for C++ with both SAX/DOM style API

  

have a look at rapidjson for a a nice simple json framework https://rapidjson.org/ I use it and it's quite fast and as good as anything I used in python.
