From your own results, scanning 10000 mounts through mountfs and reading just
two values from each is an order of magnitude slower without the effect of the
dentry/inode caches. It gets faster on the second run because the mountfs
dentries and inodes are cached - but at a cost of >205MiB of RAM. And it's
*still* slower than fsinfo().
