Linux While Ext4 was originally merged in 2.6.19, it was marked as a development filesystem. It has been a long time coming but as planned, Ext4dev has been renamed to Ext4 in 2.6.28 to indicate its level of maturity and paving the way for production level deployments. Ext4 filesystem developer Ted Tso also endorsed Btrfs as a multi-vendor, next generation filesystem and along with the interest from Andrew Morton, Btrfs is planned to be merged before 2.6.29 is released. It will follow a similar development process to Ext4 and be initially marked as development only.

Member since:

Is ext4 less prone to performance degradation on filesystems with less space for defragmentation?

I've read that it improves this situation somewhat but no specifics thus far.

I've been using ext4 for the last 3 months (Linux 2.6.26+latest ext4 patch). So far, no problems that me or fsck could detect, so it looks rather stable for a file system in development.

Generally speaking, directory operations (with lots of files) are a lot faster, and so is deleting large files. However, as the disk fills up, performance drops a lot.

Anyway, it is an improvement over ext3 and once it's done I'll probably switch completely to it.
