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.

From slow to SIMD: A Go optimization story
I wonder whether avo could have been useful here?[1] I mention it because it came up the last time we were talking about AVX operations in go.[2]

How to Use AVX512 in Golang
I thought the /r/golang comments on this post were pretty useful[1]. They also introduced me to avo[2], a tool for generating x86 assembly from go that I hadn't seen before. There are some examples listed on the avo github page for generating AVX512 instructions with avo.

For writing AVX512 from scratch avo is a much better alternative.

SIMD Accelerated vector math
Avo is a library that simplifies writing complex go assembly, I found it very useful to figure out how instructions map onto Go's asm syntax. But you could definitely do the translation directly, it's what c2goasm did (couldn't get it to work reliably unfortunately).

HaxMap v0.2.0 released, huge performance improvements and added support for 32-bit systems
Curious if you're looking at using avo to write the assembly
-
HaxMap, a concurrent hashmap faster and more memory-efficient than golang's sync.Map
You can use github.com/mmcloughlin/avo for generating the assembly use Go.

S2: Fully Snappy compatible compression, faster and better
For normal and "better" mode I am using avo to generate different encoders for different input sizes, with and without Snappy compatibility. That currently outputs about 17k lines of assembly.

Branchless Coding in Go (Golang)
You could perhaps just have the Go compiler generate the assembler for your code:
go tool compile -S file.go > file_amd64.s
Then you could verify it doesn't change over time, and choose to begin maintaining by hand if it makes sense.
If you do want to go the route of rolling it yourself, I'd suggest looking into something like Avo: https://github.com/mmcloughlin/avo

High precision timer loop.
If you have to go with Assembly, try Avo https://github.com/mmcloughlin/avo

Quickly checking that a string belongs to a small set
We took a similar approach in our JSON decoder. We needed to support sets (JSON object keys) that aren't necessarily known until runtime, and strings that are up to 16 bytes in length.
We got better performance with a linear scan and SIMD matching than with a hash table or a perfect hashing scheme.
See https://github.com/segmentio/asm/pull/57 (AMD64) and https://github.com/segmentio/asm/pull/65 (ARM64). Here's how it's used in the JSON decoder: https://github.com/segmentio/encoding/pull/101

Changing one character wildly improved our application's performance
OP here, the algorithms we use give us about 5-10x the performance of the standard library sort, even compared against the new pdqsort in Go 1.19. https://github.com/segmentio/asm/pull/77

sha256-simd - Accelerate SHA256 computations in pure Go using AVX512, SHA Extensions for x86 and ARM64 for ARM. On AVX512 it provides an up to 8x improvement (over 3 GB/s per core). SHA Extensions give a performance boost of close to 4x over native.
