moss: Add filesystem baseline performance data

Just to have a set of simple baseline numbers for future reference, a set
of informal data were captured on clean installs of Serpent OS on the same
i7-6700K system with an older SATA-600 MLC harddrive.

The filesystems tested were ext4, f2fs and xfs w/ kernel 6.12.
