Linux 3.6 Released

Posted by samzenpus on from the brand-new dept.

diegocg writes "Linux 3.6 has been released. It includes new features in Btrfs: subvolume quotas, quota groups and snapshot diffs (aka 'send/receive'). It also includes support for suspending to disk and memory at the same time, a TCP 'Fast Open' mode, a 'TCP small queues' feature to fight bufferbloat; support for safe swapping over NFS/NBD, better Ext4 quota support, support for the PCIe D3cold power state; and VFIO, which allows safe access from guest drivers to bare-metal host devices. Here's the full changelog."

  1. TCP Fast Open by w1z7ard · · Score: 4, Interesting

    Sounds like a great feature! From the article:

    "Fast Open could result in speed improvements of between 4% and 41% in the page load times on popular web sites. In this version only the client-side has been merged."

    "Recursive bipartite matching"- try it!

    1. Re:TCP Fast Open by Marillion · · Score: 5, Interesting

      On the and-user client side, there may not be much noticeable improvement. But on servers and/or load-balancing front ends this type of improvement could be quite significant.

  2. BTRFS experiences? by timeOday · · Score: 4, Interesting

    I'd be interested to hear what uses people have found for the advanced features of BTRFS. (BTRFS snapshots on a RAID1 volume seem like a great /home partition?) Since BTRFS is gradually evolving it's kind of hard to get a grasp of what is currently available and trustworthy (although this approach is vastly preferable to Microsoft's approach to revolutionizing the filesystem - aim high and never deliver!)

  3. Sounds like Windows' IIS by PhrostyMcByte · · Score: 4, Interesting

    This sounds a bit like they generalized the clever latency-saving behavior of IE which skips the TCP handshake when talking to IIS and leaves connections half-open. Latency could indeed be greatly improved for servers supporting it.
