Package: linux-image-amd64 Version: 6.11.4-1 Severity: wishlist X-Debbugs-Cc: rrosner5@gmail.com Dear Maintainer, ZRAM is quite a helpful feature to avoid swapping to storage. As it seems, the Debian config only allows for lzo and lzo-rle compression by default. As LZO is (according to the zramswap config) not only not the most efficient, but also the slowest algorithm, I'd propose to enable additional algorithms by default, and maybe even change the default algorithm. Zstd would most likely be a much better suited default, as it's a great compromise between speed and efficiency, and users can then choose on their own if they rather want to use e.g. LZO or LZ4 instead. Best Richard

Starting with kernel 6.12 ZSTD compression is no longer available for ZRAM. It used to be available by default. LZO is one of the worst compression algorithms for ZRAM and a lot of users expect ZSTD to be available. I would really like to see Debian enable all the compression algorithms as now I have to use a worse compression algorithm that will effect the performance of my ZRAM swap. Konomi

Package: src:linux Version: 6.12.3-1 Followup-For: Bug #1086172 Dear Maintainer, You need to add CONFIG_ZRAM_BACKEND_LZ4=y CONFIG_ZRAM_BACKEND_ZSTD=y And remove CONFIG_ZRAM_BACKEND_FORCE_LZO=y It's also possible to turn on CONFIG_ZRAM_DEF_COMP_ZSTD=y instead of CONFIG_ZRAM_DEF_COMP_LZORLE=y since it looks more balanced in speed/compression -- Package-specific info: ** Version: Linux version 6.12.3-amd64 (debian-kernel@lists.debian.org) (x86_64-linux-gnu-gcc-14 (Debian 14.2.0-8) 14.2.0, GNU ld (GNU Binutils for Debian) 2.43.50.20241204) #1 SMP PREEMPT_DYNAMIC Debian 6.12.3-1 (2024-12-07)
