Improve data compression performance on AWS Graviton processors
If you have applications using zlib make sure to check alternative versions of the library. Cloudflare zlib is a good one, and there may be others available. Watch the AWS Graviton Getting Started for the latest information.

How are zlib, gzip and zip related? What do they have in common and how are they different?
A faster zlib fork is available in https://github.com/cloudflare/zlib but it's not rebased on top of the latest upstream and is not packaged for debian.

Quite OK Image is now my favorite asset format
> The QOI benchmarks shows it only lagging a small bit behind PNG in compression ratio, while performing much faster (multiples) in both encoding and decoding.
Presumably that’s with stock libpng, which uses zlib. I wonder if anyone tried patching it to use the substantially faster (on x86) libdeflate[1] instead? It doesn’t do streaming, but you shouldn’t really need it for PNG textures.

Computing Adler32 Checksums at 41 GB/s
Note that libdeflate has used essentially the same method since 2016 (https://github.com/ebiggers/libdeflate/blob/v0.4/lib/adler32...), though I recently switched it to use a slightly different method (https://github.com/ebiggers/libdeflate/blob/v1.12/lib/x86/ad...) that performs more consistently across different families of x86 CPUs.

Zlib – a spiffy yet delicately unobtrusive compression library
Going away from Zlib proper but staying with its format, there’s libdeflate[1], an implementation that’s substantially faster on modern machines but can’t stream, and of course Zopfli[2], a glacially slow compressor that’s somewhat better (and occasionally much more so).
