CONFIG_SQUASHFS_COMPILE_DECOMP_MULTI: Use multiple decompressors for parallel I/O

General informations

The Linux kernel configuration item CONFIG_SQUASHFS_COMPILE_DECOMP_MULTI:

• prompt: Use multiple decompressors for parallel I/O
• type: bool
• depends on: (none)
• defined in fs/squashfs/Kconfig
• found in Linux kernels: 6.2–6.12, 6.13-rc+HEAD

Help text

By default Squashfs uses a single decompressor but it gives poor performance on parallel I/O workloads when using multiple CPU machines due to waiting on decompressor availability.

If you have a parallel I/O workload and your system has enough memory, using this option may improve overall I/O performance.

This decompressor implementation uses up to two parallel decompressors per core. It dynamically allocates decompressors on a demand basis.
