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.

Handling high-traffic HTTP requests with JSON payloads
Since most of the time would be spent decoding json, you could try to cut this time using https://github.com/bytedance/sonic or https://github.com/json-iterator/go, both are drop-in replacements for the stdlib, sonic is faster.

A Journey building a fast JSON parser and full JSONPath
We all know the builtin golang JSON parser is slow.
How about doing comparisons against other implementations?
Like this one: https://github.com/json-iterator/go
-
Polygon: Json Database System designed to run on small servers (as low as 16MB) and still be fast and flexible.
Json-iterator (https://github.com/json-iterator/go), you can replace all of encoding/json with this. It does the same thing but it's faster.

How can we umarshal a Big JSON effectively?
Do you want to look at every field all at the same time? If not, you can pick out individual fields. There's other packages such as https://github.com/tidwall/gjson or https://github.com/json-iterator/go that let you pass in paths such as "a.b.c" to extract single fields.

Designing a config API for microservices applications built using Go
For each Go type used within the config, we generate a separate unmarshaller function. The unmarshallers use json-iterator to process the output from CUE, while tracking the path within the config to the unmarshalled value. This path tracking will allow the function to check if live overrides have been provided on that path and return the override instead.

What type of software do you write at your workplace?
https://github.com/json-iterator/go an alternative JSON encoding package which allows to stream (flush out) encoded data as soon as it's able to (which is in contrast with the stock package which buffers everything until the encoding is known to be complete and OK).

Some Go(lang) tips
What to use Easyjson is about the top of the pack and it's straightforward. The downside of efficient tools is that they use code generation to create the code required to turn your structs into json to minimise allocations. This is a manual build step which is annoying. Interestingly json-iterator also uses reflection but it's significantly faster. I suspect black magic.

What are your favorite packages to use?
jsoniter for low level access to JSON encode and decode

What is the best solution to unique data in golang
Takes like 10 minutes to write and parses very efficiently. https://github.com/json-iterator/go looks like it can provide such simple parsing

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.

80x improvements in caching by moving from JSON to gob
If you need to support non-Go code I suggest you explore CBOR. There are a few implementations in Go but his is my favorite.
What are some alternatives?
go-json - Fast JSON encoder/decoder compatible with encoding/json for Go
asn1
mapstructure - Go library for decoding generic map values into native Go structures and vice versa.
goprotobuf - Go support for Google's protocol buffers
easyjson - Fast JSON serializer for golang.
gogoprotobuf - [Deprecated] Protocol Buffers for Go with Gadgets
go-capnproto - Cap'n Proto library and parser for go. This is go-capnproto-1.0, and does not have rpc. See https://github.com/zombiezen/go-capnproto2 for 2.0 which has rpc and capabilities.
