arstechnica.com — The Ext4 filesystem, which was officially declared stable in Linux kernel 2.6.28, is now available in the latest Ubuntu 9.04 daily CD builds. Preliminary benchmarks show that it delivers significantly better performance.

Nice... I'll have to update my kernel and see if I can convert my ext2 partitions on my eeepc.

I didn't bury you because you posted the full article link which is useful, but:1) The "nicked" graph was not an aberration, and the performance gains were not minimal based on any kind of reasonable expectations. The other graphs all show a range between par and doubled performance, which is pretty awesome considering that the same volume of work was being done on the same physical hardware. How much improvement can you possibly expect in use cases that are unalterably bottlenecked by raw hardware bandwidth or latency?2) We were already well aware that benchmarks by nature are generally synthetic. That does not automatically invalidate the measurements, especially when they represent a best genuine effort to do exactly that--measure performance. Also keep in mind that this isn't like measuring graphics performance where there's a lot of performance interdependency between memory, graphics, and general processing...this is a single isolated subsystem that is virtually never bottlenecked by anything else (unless you go out of your way to bring network performance into the picture). With all the effort that goes into simulating realistic usage patterns, I wouldn't be so quick to jump to such a FUD-like conclusion.

He uses a different computer though before and afterwards. So the 10 seconds could be just from that

Linux users don't care to write them. There's a ext2 driver that I use on the few instances I need my ext3 drive data.

They finally perfected that? I know on XP they had the laggy mouse and every now and again you'd see the frozen mouse feature, but man. Maybe I should switch back. ubuntu just has normal speed mouse, I've been ripped off.

Wait, I use Fedora, but I'm a "dick fanboy" because I think it's stupid to hate Ubuntu?Right...
