Written by Michael Larabel in Software on 15 December 2011. Page 3 of 3. Add A Comment

At least NILFS2 is able to pull in front of Btrfs when it comes to the SQLite benchmark, but EXT4 remains in first.

When carrying out a 8GB write using a 4Kb block size, Btrfs and EXT4 were both running at the same speed while NILFS2 was left in the dust.

For 64kb and 1MB record sizes, Btrfs and EXT4 remained close while NILFS2 struggled to be competitive.

The 8GB read performance with IOzone was at least comparable under the Btrfs and NILFS2 file-systems while EXT4 still managed to secure first place.
