> Amazon recommends the use of cloudflare's zlib implementation at [https://github.com/cloudflare/zlib]
> In a blog post, they claim pretty large performance boosts over the regular zlib implementation:
> [https://aws.amazon.com/blogs/opensource/improving-zlib-cloudflare-and-comparing-performance-with-other-zlib-forks/]
> {noformat}
> On Arm:
>   Compression performance: ~90 percent faster than zlib-madler (original zlib).
>   Decompression performance: ~52 percent faster than zlib-madler.
> On x86:
>   Compression performance: ~113 percent faster than zlib-madler.
>   Decompression performance: ~44 percent faster than zlib-madler.{noformat}
> The blog post is a year and a half old, so things may have changed since then, but it seems interesting. Amazon's guidebooks still recommend it.
