Note that FreeBSD in the benchmark is running with LZ4 ZFS compression on which works like a speed miracle for read only database tests. ZFS with compression doubles the read bandwidth of the disks will close to double the database benchmark speed.

In Linux one would need to benchmark BTRFS with LZO compression to benchmark compete against FreeBSD ZFS with compression.

In the linked article, FreeBSD+zfs was half as fast as linux on the read only tests.
