Has anyone here used e4defrag? I used it today and i did not notice any performance improvement. Then again ext4 dosent really need to be defragged in the first place. I had about 29 fragmented files and was curious on how files are defragged. Apparently this defragmenter only defrags files not free space, so i guess a negative thing about using this defragmenter is that free space will probably become more fragmented.
