How I cut GTA Online loading times by 70%

But C++ had at least a hash_set/hash_map since forever (or just set/map which are still better than this)

I'm sure there are libraries to parse json in C++ or at least they should have built something internally if it's critical, instead they have someone less experienced build it and not stress test it?

There certainly are, but adding a library is much more difficult in C++ than pretty much any other language which seems to tempt people into hacky self-built parsing when they really ought to know better.

The first C++ JSON library that appears when you google it is a single header file.

https://github.com/nlohmann/json

I know because I used it years ago in school.

One of the fastest libraries (https://github.com/miloyip/nativejson-benchmark#parsing-time) is also header-only and compares its speed to strlen.
