alt Hacker NewsAnd not a word about MGLRU and its settings. It has the biggest impact on performance on lower-end PCs, especially with low amount of RAM and slow HDD.
Here's a post from "le9" patch user which was created by ChromeOS developers much before MGLRU, but exploits the similar idea: keeping the essential file cache in RAM for as long as possible. It's usually night and day on low-end machines.

I had never heard of it, but checking it, I see MGLRU is enabled by default on my kernel (Mageia 10 with 6.18.xx). Are there distros where this is not enabled? Especially the ones mentioned in the blogpost? In that case it would need a recompile of the kernel, right? Or send in a bugreport to the distro.
