Linux Kernel in system performance

Linux Kernel for system performance-general Linux technology-Linux programming and kernel information. The following is a detailed description. The originally installed linux version is the red-flag desktop version 6.0, which is later upgraded to sp1 and kernel to 2.6.23. I tried to upgrade his kernel to a newer version, but the latest version is 2.6.26.2. However, because my nvidia graphics card driver and the latest driver are not compatible with the kernel, therefore, we can only continue using the old kernel. We saw that the Linux kernel was upgraded to 2.6.26.5 two days ago, and we also released a new driver to nvidia. In addition, we mentioned that this improved the compatibility with the linux2.6 kernel, as a result, the idea of upgrading the kernel emerged, and everything went smoothly. The upgrade was successful, and the system performance was greatly improved compared with that before the upgrade (although I did not perform a detailed test, only by feeling), the original window was jittery, not smooth Russian feeling, after the upgrade late system interface reaction is much happier than the original, drag the window without the original jitter, blocking, and other non-smooth feeling.

Because my kernel and drivers have been upgraded, some kernel compilation options are for my computer (AMD dual-core processor, in addition, I added some drivers that I may use and removed several options that I don't think I will use. Most of them use the default values). Therefore, the performance improvement should be related to these aspects, especially for Kernel compilation options, the original release version will adopt general options for processor compatibility, and some specific processor features cannot be better utilized, therefore, I think we should try to compile the kernel on our own if possible.
