Help text

By default SquashFS caches the last 3 fragments read from the filesystem. Increasing this amount may mean SquashFS has to re-read fragments less often from disk, at the expense of extra system memory. Decreasing this amount will mean SquashFS uses less memory at the expense of extra reads from disk.

Note there must be at least one cached fragment. Anything much more than three will probably not make much difference.
