"slow" is really subjective, meaning that your feeling may not be mine, it depends on your expectations, what you know and didn't told us and what you do with your computer. Do you feel a global slowness, micro hangs, long hangs, mouse or keyboard not responding, GUI not responding, unusual timings of specific commands? Is this constant or fluctuating? As mentioned by another here, CPU could run slow, for various reasons (for instance: overheat, often because the cooling system is in bad condition or cannot compensate global conditions). What does `top` command show (sort by cpu usage), any CPU-eating apps? Mostly, the amount of RAM is not going to slow down things unless you are eating more memory than you have RAM, then you're swapping (read: using disk as live memory), this is easy to determine. Doubling the RAM only (mostly) speeds up by avoiding swapping, rarely a perceptible effet if not swapping. What's the amount of free swap (`free` command, line Swap, row free), and total memory (`free`, line Mem, raw total). Bad memory modules could slow things down, but would certainly cause crashes. Too few memory would cause swapping then kernel killing big apps. Also: bad sectors on disk may cause slowness or hangs. Other hardware/kernel-related issues will be harder to find. Are you able to run hardware diagnostics/tests on this system? (various brands provide such tools available at boot time) Regards, -- wwp https://useplaintext.email/
