Ubuntu 9.04 Receives EXT4 Support

[WSmart]

I'm excited about Solaris ZFS. Wonder how that would stack up.

Surprising how poorly EXT3 did.

Ext4 was released in Fedora 10, and will also be released as a tech preview with Red Hat Enterprise Linux 5.3.

You act like Ubuntu is trailblazing here.

That is total BS, he did benchmarks before with fedora 9, and even mentioned that fedora had it in their distro well before ubuntu did.

"While the EXT4 file-system was marked as "ext4dev" within the kernel to signify its development status, Red Hat has been shipping EXT4 as an install-time option since Fedora 9. This support has continued into Fedora 10 with the newest kernel components. When installing Fedora, to create an EXT4 file-system you must append "ext4" to the boot line when starting the Anaconda installer. Beyond the Fedora option, EXT4 has yet to find itself as an option in many distribution installers."

Could you please test random write performance? The tested ssd has horrible (re)write-latencies, and filesystems can have a significant impact on that(the more small writes, the worse).
Mine's currently running udf...

This test will probably affect what fs I will format my newly cleared 250 gb disk to. Although speed of the fs is a concern I am also concerned about being able to put the drive to sleep. Currently I have mounted my ext3 disks as ext2 so the journal wont be written every 5 sec which makes it impossible to put them to sleep with hdparm -Y /dev/sdX

I read somewhere that MySQL performance was much improved with ext4 - does PTS have any MySQL or PostgreSQL benchmarks?

Please conduct a test with the latest version of btrfs.

Thanks

I thought BetterFS wasn't even fully implemented yet, or can it do most all the basics already? Regardless, I'm sure it won't be nearly as fast as later on when everything gets stabilized more, but benchmarks of it would indeed be interesting.

And don't forget Tux3! ^^

As far as EXT4 is concerned, it looks great, thanks for the benchmarks!

Were these tests done on the hardware with a clean install each time with each file system as big as the others and occupying the same disk geometry?

Yes, we always do fresh installs each time.
