In this issue, the editor will bring you an example analysis of how Linux Kernel 2.6.35 improves network performance. The article is rich in content and analyzed and described from a professional point of view. I hope you can get something after reading this article.

Another quarter has passed, and Linus Torvalds has also released the official version of the Linux Kernel kernel: 2.6.35 on schedule. This is the mainline version of the Linux kernel (mainstream).

The main features of Linux kernel version 2.6.35 are:

◆ comes from Google's Receive packet steering (receive packet manipulation)

◆ from Google's Receive flow steering (receive stream manipulation)

◆ memory Compression (Memory compaction)

◆ 's direct iUnip O support for Btrfs

◆ added a new driver

Two new features donated by Google can distribute the load of network processing among multiple CPU of the system and improve the performance of network processing.

Linux 2.6.35 Kernel introduces ATI power management support for Radeon KMS open source graphics card drivers, Intel H.264 VA-API video acceleration support for the new Intel GMA integration chipset, Radeon DRI2 synchronization and switching, Btrfs file system improvements, RPS and RFS support for core distribution of network incoming load processors, and so on.

On the performance side, Linux 2.6.35 Kernel experienced a brief severe performance degradation until the end of May, but fortunately it was quickly fixed and everything is now fine. Overall, the performance of the new kernel is about the same as that of the previous version, except for the Btrfs file system.

Linus Torvalds also announced a new policy that will strictly restrict new code to the Git code tree after the release of the new kernel RC1 candidate version, in order to greatly reduce the maintenance workload. In the next Linux 2.6.36 Kernel, he will continue to adhere to this policy.

The above is the analysis of the example of improving network performance of Linux Kernel 2.6.35 shared by Xiaobian. If you happen to have similar doubts, please refer to the above analysis. If you want to know more about it, you are welcome to follow the industry information channel.
