I have seen the ext4 benefits including dramatically faster
fsck times on large file systems.
The only issue I've seen is the long time it takes to unmount a
file system, even one that has been inactive for a few minutes.
Do you see that every time you unmount?
Thanks to delayed allocation there may be a fair amount of IO waiting,
