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.

Go 1.20 Released
Glad to see this make it into the core.
I've been using this library for ages now...
https://github.com/cornelk/hashmap
Always entertains me to see developers write all the lock/unlock code when they could just use that.

HaxMap, a concurrent hashmap faster and more memory-efficient than golang's sync.Map
Assuming it is issue 54 and its age, I am now unsure about the usability.
Pre-allocating would not fix https://github.com/cornelk/hashmap/issues/47 as the bug is in the linked list. This is not grow related but an issue with concurrent Add/Delete on the list.

A Go implementation of the concurrency control algorithm in paper <Left-Right -A Concurrency Control Technique with Wait-Free Population Oblivious Reads>
Would be interesting to compare with https://github.com/cornelk/hashmap

SIMD in Go
You can find a pure go unparallelized version here : https://github.com/pierrec/xxHash

HaxMap, a concurrent hashmap faster and more memory-efficient than golang's sync.Map
I shall add a 32 bit variant of haxmap too in the near future using this 32 bit variant of xxHash https://github.com/pierrec/xxHash/tree/master/xxHash32
What are some alternatives?
go-left-right - A faster RWLock primitive in Go, 2-3 times faster than RWMutex. A Go implementation of concurrency control algorithm in paper <Left-Right - A Concurrency Control Technique with Wait-Free Population Oblivious Reads>
sonic - A blazingly fast JSON serializing & deserializing library
haxmap - Fastest and most memory efficient golang concurrent hashmap
pq - Like jq, but with Python
immutable-js - Immutable persistent data collections for Javascript which increase efficiency and simplicity.
go - The Go programming language
query-json - Faster, simpler and more portable implementation of `jq` in Reason
jqr
go-evmap - A Go implementation of Rust's evmap which optimizes for high-read, low-write workloads and uses eventual consistency to ensure that readers and writers never block each other.
garr - Collection of high performance, thread-safe, lock-free go data structures
