Kernel 2.6.31 to speed up Linux desktop
With the next version of the Linux kernel, 2.6.31, due for release soon, Linux desktop users can look forward to a faster experience in addition to USB 3.0 support and new Firewire drivers.
The kernel developers have been working on improvements to desktop interactivity, particularly when it's under memory pressure since the last release, version 2.6.30, in June.
Desktop applications can experience long and noticeable pauses when the application's code path jumps to a part of the code that is not cached in memory and needs to be read from the disk, which is slower.
However, recent kernel memory management scalability work can result in a desktop environment with poor interactivity as applications become unresponsive too easily.
