Google To Switch To EXT4, Hires Ted To Code

“Google is in the process of migrating their EXT2 file-systems
over to the modern EXT4 file-system. This was brought up in a JFS
benchmarking discussion. Google’s Michael Rubin shared that they
chose EXT4 after benchmarking it as well as XFS and JFS (possibly
with our Phoronix Test Suite carrying out some of the testing,
which they have used in other areas). Their results showed EXT4 and
XFS performing close to one another, but with it being easier to
upgrade from EXT2 to EXT4 rather than EXT2 to XFS, they went with
the easier path.”
