Ext4 just isn’t ready
An independent study has shown that as the linux kernel is changing, ext4 isn’t keeping track with the changes. Not to say ext4 isn’t good, it’s just not as fast as ext3 with the current newer kernel changes. A shame really, as I was a fan of the idea of ext4 (who wasn’t?).
Again, this testing was looking at the file-system performance when each file-system was left to its default mount options. EXT4 could be mounted in a way that it would not suffer as many performance penalties (at the risk of data being potentially lost in a crash) and the other file-systems can be tuned as well, but we will save that tuning and mount option testing for another article.
