Ubuntu, Kubuntu, Xubuntu "UDS is over! And in the customary wrap-up I stood up and told the audience what the Foundations team have been discussing all week. One of the items is almost certainly going to get a little bit of publicity. We are going to be doing the work to have btrfs as an installation option, and we have not ruled out making it the default. I do stress the emphasis of that statement, a number of things would have to be true for us to take that decision."

Simply because Ext4 is crap and very slow. Even Ext3 is MUCH faster than Ext4. Btrfs is quite usable already and already outperforms Ext3 and Ext4 in many (most) tests.

Also, just because a distro makes some or other filesystem the default, doesn't mean you as an end-user needs to you use that default. The installation allows you to choose any file system you like.

And when in doubt about a file system, do what I do. Make one of your non-bootable partitions (eg: /opt) the file system in doubt. Then play around with it, copy/read files from it, play movies form it. Do software compiles from it. If it doesn't work out for you or doesn't perform to your expectations, simply copy the data off and reformat that partition with a different file system. It's not that damn difficult.

I think Ubuntu has a good idea. Put Btrfs out there so it gets some exposure - that's the only way software improves really fast.

From April, but the general consensus is that ext4 is the best overall filesystem.

And a big warning is there too. DO NOT ATTEMPT TO RUN postgreSQL on BTRFS. The one real life example, btrfs chokes and dies on (doesn't crash, just crawls).

While Phoronix is great for news around Xorg (they do a lot of original research on this topic by following mailing lists, etc.), Phoronix' benchmark methodology is usually flawed. Somebody once even made the joke that Phoronix would benchmark Linux distros by comparing the CD images' checksum and the higher one "wins".

No real surprise considering Btrfs was only recently put in the Linux kernel. Now that most/many Btrfs features have been implemented and the on-disk storage format has been set, now it needs to be tested in the wild and performance tuning can start. Btrfs with compression already outperforms Ext4, and ext4 has been around for some time now. That tells you something!

I'm definitely eager to try Btrfs with compression enabled (this is what I loved about ZFS's idea too). With today's fast hardware and the hard drive being the biggest bottleneck in any system - compressing data means reading less data off the hard drive - which will translate to increased system speed.
