On a lot of blogs and QA sites, you’ll find the recommendation to, if you have a low-RAM Linux desktop or laptop, to reduce vm.swappiness, the tuning knob that tells the kernel how much to prioritize moving unused application memory to swap to free up memory for the cache. It’s commonly recommended to reduce it to 10, and many guides recommend reducing it to extreme values like 0 (disable swap) or 1 (swap only when the only other option would be to OOM-kill processes).
