It's Tux3 versus Ext4 !

46.338, 1.244, 5.096

44.011, 0.684, 1.764
43.773, 0.556, 1.888

Looks like almost 3 times faster than ext4. great improvement.👍

Update : Tux3 File-System is even faster than tmpfs as per latest benchmarking result.The reason given by Daniel Phillips for Tux3 being able to outperform tmpfs is that Tux3 back-end/front-end design can work atop CPUs & when some task is offloaded a-sync for dbench task, the result comes out to be positive.

However, sad thing is Tux-3 File-system still hasn't been proposed for inclusion in mainline Linux Kernel.Atleast we are not going to see inclusion of Tux3 in Next Kernel Update i.e. Linux Kernel 3.10
Maybe sometime soon ?

What's your take CEans ? Do you think Tux3 will replace the current FS of Linux i.e. ext4 ?

It should, provided it is stable after completion of development phase. If it is faster, which it is, then I guess it should be used.

Update:
Tux3 BTree based FS still isn't included in mainline Linux Kernel.However, Tux3 team is concentrating in adding new features to this File-system which has outperformed Ext4 in the initial benchmarking.

More details by lead developer Daniel Phillips has been published about Data compression in the mail listing.The latest update claims that, Tux3 is aiming for transparent data compression on complete file-system & per file-levels.

Tux3 is constantly being developed & new features are added. But still it's not stable FS for Linux.Hence, there is no hope that it will be merged in Linux mainline Kernel in next update of Linux Kernel 3.11

Update:
The linked PDF includes overview on Tux3 FS which was submitted in LinuxCon 2013. It covers every features of Tux3.

And another update :
It's been five years of Tux3 development, and still it is not mainlined in Linux kernel. Well, you have to wait some more time since there are still some extraordinary bugs which is pushing back the stable release.

Update :
Finally! Good news. It's been reported by Phoronix that Tux3 is likely to be merged into Linux Kernel in a week or two. Let's wait for merge proposal. I am keen to test this FS 👍

Update :
Tux3 was harshly criticized by XFS developer Dave Chinner Over its Code Quality. It's been said, Tux3 even after 6 years of development is at the stage where Btrfs was 5 years ago. So, Tux3 still have long way to go.
