Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

API: Go, .NET, Rust
For go -> you can actually get away with the standard json encoding package. Or if you want a slightly better one, I prefer goccy/go-json

Rob Pike: Gobs of data (2011)
Someone made a benchmark of serialization libraries in go [1], and I was surprised to see gobs is one of the slowest ones, specially for decoding. I suspect part of the reason is that the API doesn't not allow reusing decoders [2]. From my explorations it seems like both JSON [3], message-pack [4] and CBOR [5] are better alternatives.
By the way, in Go there are a like a million JSON encoders because a lot of things in the std library are not really coded for maximum performance but more for easy of usage, it seems. Perhaps this is the right balance for certain things (ex: the http library, see [6]).
There are also a bunch of libraries that allow you to modify a JSON file "in place", without having to fully deserialize into structs (ex: GJSON/SJSON [7] [8]). This sounds very convenient and more efficient that fully de/serializing if we just need to change the data a little.

Data storage speed comparisons?
Drop-in replacement for the stdlib JSON package: https://github.com/goccy/go-json

Go is 2-3 times slower than JS in a similar code. What makes Go slow in this specific code?
go stdlib json encoding/decoding is incredibly slow, not sure for how much longer because there are drop in replacements now that I think are just as strict and feature parity.

Go with Chi has more ram consumption and less req/s than Koa or Fastify
3rd party JSON libraries could help if you were comparing JSON. https://github.com/goccy/go-json

ogen: spec-first OpenAPI v3 codegen for Go
However, I understand the code that is generated is super optimized. For example, rather than use a router, it does a static code generated router. Rather than use goccy/go-json, it does manual marshalling.

japi is a JSON HTTP API go library with generics
Minimal dependencies: julienschmidt/httprouter and goccy/go-json

Using a json lib other than encoding/json
I suggested using https://github.com/goccy/go-json at my work, since its a drop in replacement for the standard lib, but there are people who apprehensive. In my opinion the performance gains are significant to justify adoption. But I'd like your input.

Take the output of your statement and run it through https://github.com/davecgh/go-spew spew.Dump. It will not be what you expect. See if that helps. If not, ask more questions.
