@ -67,13 +67,6 @@ Most other options are concerned with compression tuning:
to the number of processors available on your system. Use this option if
you want to limit the resources used by `mkdwarfs`.
* `-M`, `--max-scanner-workers=`*value*:
Maximum number of worker threads used for building the filesystem. This
defaults to the number of processors available on your system, but the
number of active workers will be automatically adjusted based on load.
With fast SSDs, scanning multiple files is probably fine, but with older
spinning disks, having less concurrency can improve overall speed.
* `-L`, `--memory-limit=`*value*:
Approximately how much memory you want `mkdwarfs` to use during filesystem
creation. Note that currently this will only affect the block manager
