Subject: Maybe we can set default zstd compression level to 1 when SSD detected?
Date: Sun, 13 Apr 2025 12:07:26 +0800 [thread overview]
Message-ID: <8c2e5d04-dbda-4b12-992e-34f0e70c7218@archlinuxcn.org> (raw)
Hi,
When SSD is detected, maybe we can set default zstd compression level to 1.
Current default compression level for zstd is 3, which is not optimal
for SSDs.
This GitHub Gist [1] can serve as a reference.
An example is Fedora Workstation [2], which uses `zstd:1` as default
compression option.

Sincerely,
