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?
