Тест современных компрессоров для HTTP

Сжатие текста уже давно стало стандартом в мире веб‑приложений. Сокращение объёма данных даёт сокращение времени передачи и снижение нагрузки на сетевой канал. Однако, часто настройка компрессии сводится к динамическому сжатию gzip и настройкам по умолчанию. В этой статье разберём вопрос сжатия более глубоко. Для начала вспомним основные технологии сжатия, доступные в вебе.

Creating .tar.zst archives on Windows doesn’t require extra software. The native tar command already supports Zstandard (zstd). Simply add the context menu option to get started: https://github.com/SamiLehtinen/CompressTarZstd #Windows #Zstandard #Zstd #compression

Nice! Btrfs with Zstd fast modes can significantly boost read performance for compressible data. #Linux #Zstandard #btrfs #datacompression

Today I discovered that there is also an excellent compression format, #Zstandard (ZSTD), is fast with an excellent compression ratio, developed by #Meta, and released as #opensource
I needed to backup my files because I have to wipe my PC and reinstall #Linux. Now I have a dilemma: choosing between #antiX and #Lubuntu. I have a fairly decent computer, so I could even install a more full-featured OS, but I prefer an OS that doesn’t use too many resources.

Brand new PEP by @emmatyping to add Zstandard to the standard library:
https://peps.python.org/pep-0784/

Will it make it in to 3.14 before the feature freeze on 2025-05-06? It'll be close but it's possible!

The PEP also suggests namespacing the other compression libraries lzma, bz2 and zlib, with a 10-year deprecation for the old names.

#OpenSource #Zstandard

My #Zstandard decompression browser test pages now actually works in Chromium and Firefox (with the right experimental flags enabled). Before today, the decompression test was accidentally double-compressed. Zstd is on the track to be enabled by default in Chromium. #WebDev
https://www.daniel.priv.no/tools/zstd-browser-test/

#TIL that #Zstandard is supported in HTTP compression (RFC 8478). There's also some guy out there who wrote an #NGINX module to implement it. https://github.com/tokers/zstd-nginx-module

One custom build of NGINX later, a few additions to my precompression script, and ngx_http_zstd_static_module is now serving zstd-compressed assets to any compatible browser that visits my web site. That's currently only Chromium (masked behind a flag), but hey, it's ready whenever the browsers catch up.

#Zstd, in practice, is worse than #Brotli but better than Gzip. It's also faster than both!
