Compared to both lzo and zlib, zstd is the best all-around performer. Backport a kernel patch [1] (to both 5.4 and 5.10), in order to set it as default for ubifs, if available.

Subject: [PATCH] ubifs: default to zstd compression
|
|
|
|
Compared to lzo and zlib, zstd is the best all-around performer, both in terms
|
|
of speed and compression ratio. Set it as the default, if available.
