I looked into lossless compression options in OpenEXR and write a small post with the findings. Next up, trying to add/tweak more compression thingies! https://aras-p.info/blog/2021/08/04/EXR-Lossless-Compression/
@firstname.lastname@example.org I wonder, how would using Cloudflare's fork of zlib improve performance? AWS reports it being a lot faster than the main branch of zlib https://aws.amazon.com/blogs/opensource/improving-zlib-cloudflare-and-comparing-performance-with-other-zlib-forks/
@ignaloidas and I did try libdeflate here: https://aras-p.info/blog/2021/08/09/EXR-libdeflate-is-great/
@email@example.com Yeah, but hstlib benchmarks are a quite old, and AWS contributed the decompression performance improvements quite recently. I don't expect compression speeds to be higher, but decompression speeds might be higher with it, since some patches claim 30% improvement.
