Subject: ext4 performance benchmarks

Hi Guys,

The following article says that ext4 performance has plummeted
since the 2.6.31 kernel. Can someone please comment on this?

http://www.phoronix.com/scan.php?page=article&item=ext4_then_now&num=1

Are large reads giving a lower performance for the kernels post 2.6.30?
Is this performance attributed to some particular ext4 features/patches?

Does anyone maintain the benchmarking results for ext4 after any
feature/big patches are applied?

Thanks !

Warm Regards,
Surbhi.
