IIRC we tested with EXT4 once and found XFS to be just a bit faster. But that was years ago and memory is fading.
Not sure whether it was LWN or the linux-raid list ... There's a new variant of ext4 in the works, called "lazy-ext". And it's specifically aimed at improving raid performance. Basically, the problem is that even when streaming large data files, there's a fair bit of metadata updating going on in the background. And this triggers a lot of small, random writes. Guaranteed to make a raid controller have heartburn. So there's some tweak they're testing that consolidates all these small writes into one big stream to improve performance. I can't remember the figures, but they do look good. Cheers, Wol -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
