From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

In case you don't know Multi-Gen LRU is an alternative LRU implementation that optimizes page reclaim and improves performance under memory pressure. Page reclaim decides the kernel's caching policy and ability to overcommit memory. It directly impacts the kswapd CPU usage and RAM efficiency.

Has anyone enabled this feature on their machines? Have you noticed any performance gains or memory management improvements? It's developed by Google and is reportedly is being used in ChromeOS and Android.

I jammed 64GB into my work laptop sort of by accident (I thought the original kit I ordered was 2x16GB but it was 1x32 so why not keep going) and I have no regrets. 20GB tmpfs for builds? Why not?
