learned about an incredible tool for Go programs last night called statsviz (github.com/arl/statsviz). it adds a debug webpage to your program with a very snappy live visualization of runtime stats. useful for understanding GC behavior!

We heard you wanted smaller binaries: [alt] Graph shows recent progress in total binary size over time, 1.16 & 1.17 dev against 1.15. Total geomean size down 9.3%, text down 17.2%. Performance, geomean time down 4.5%. (This was a (big) team effort.)

Learn how the engineering team solves hard problems and uses the Roaring bitmap encoding format to efficiently manipulate integer sets on ARM64.

gzhttp: Easy to use, fast #golang gzip "middleware" for stdlib HTTP handlers and client transports. Forked/based on nytimes/gziphandler and approx 2x faster with fewer allocations and many other improvements. Check it out at github.com/klauspost/comp…

Go’s place between C and Python in terms of abstraction and garbage collection memory management model has made it attractive to programmers looking for a fast but reasonably high level language. However, there is no free lunch. Go’s abstractions, especially…

Recommended: Shift-based DFAs, by @pervognsen. gist.github.com/pervognsen/218… Tried it out for replacing Go's utf8.Valid. Don't get to see this very often:

Experimental implementation of a proposed v2 encoding/json package - go-json-experiment/json

This post will shed some light on how we were able to optimise one of our frontends, reducing the typical project’s run time by half…

I can confirm this. What most people don't realize is how much time is spend in mallocgc in #golang. It's death by a thousand paper cuts that is difficult to see. Here is a toy app hiding 23.7% time in mallocgc. See screenshot 2 where with focus_on(). Real…

After a number of attempts, a concurrent Map for Go is ready. It implements CLHT algorithm with a number of modifications. So far, the map looks very promising to me. github.com/puzpuzpuz/xsyn…
