Maybe Kernel 2.6.31 More Faster?

The next version of the Linux kernel 2.6.31, which should be communicated as soon we can expect a user experience of desktop Linux in addition to support fast USB 3.0 and FireWire new drivers.

The kernel developers have worked to improve the interactivity of desktop, especially when the memory pressure since the last release, version 2.6.30, in June

Desktop applications can live a long and significant pauses when the code of the application path breaks at some of the code are not stored in memory and must be read from disk, which is slower.

However, recent work of memory management kernel scalability resulted in an office environment with poor interactive applications that can respond more easily.

In version 2.6.31, a heuristic is used for much more difficult for the allocated pages executable move "from the list of active pages, according Kernelnewbies.org.

"The result is an enhanced desktop experience, benchmarks show tight memory for desktop computers and large errors in time reduced by 50 percent, and the numbers pswpin (memory reads from disk) are reduced to about third. This means X desktop responsiveness is doubled memory under high pressure".

In addition, memory benchmarks ignited in a file server provides the number of major faults range from 50 to 3 more than 10 percent cache warm bed.

Foundner Linux Linus Torvalds, the first operating system developed for its desktop and it increased to promince as commodities Unix server.

However, adoption of Linux on PCs and laptops remained niche over Windows and not become an alternative to more mainstream in recent years.

Estimates range game, how many Linux workstations are in use today, but market share data from Net Applications, Linux desktops from a peak of 1.17 percent in May 2009 and has since declined 0, 94 per cent in August.

The arrival of Windows 7 in October, conduct a market share of desktop Linux even further.

It is not so bad for the penguin, however, such as improved memory management kernel, X.org server development boards, updated graphics drivers and developments in the two main environments Desktop - GNOME and KDE - are all the Linux desktop to improve the ecosystem.

Another improvement mode with 2.6.31 kernel parameter support for ATI Radeon graphics cards.

In kernel mode moves initialization parameter in graphics mode from the startup process of the X server kernel, which allows the user to quickly change and launch a seamless experience.

Developments devices that enhance the experience of desktop Linux will include support for the new USB 3.0 specification and a new FireWire stack.

Intel has worked USB 3.0 device support for hardware that eXtensible Host Controller Interface (xHCI) 0.95 specification implements.

USB 3.0 or USB-Super Speed, UPS theoritcal the maximum data rate to 4 Gbit / s.

XHCI material is not yet available, but the kernel drivers are tested as part of Fresco Logic prototype host controller.

For Firewire, 2.6.31 brings improved support for access to fine grained authorization policies implemented in user-space programs, IP networks with the new driver stack, and support for Firewire drives more than 2 TB.

"This is no longer marked as experimental in the setup menu of the nucleus, the distributors who have provided the older driver IEEE1394 stack to date are encouraged to build both the driver and installation of chimneys", says project .

The latest release candidate for the new Linux kernel 2.6.31-rc8 August 28.
