I've set up an old laptop with Linux mint some months ago, and while the laptop's speed is fine when there are no disk write, even a very small write can cause other applications to hang until it is done, and i can also tell because i have an IO led so whenever it is on i know that i can't really interact with stuff whenever it's on.
SMART status doesn't seem to report anything, (tested some weeks ago, but issue was always present), but i'm willing to test again and show screenshots.
I'll show some maybe relevant information, note that my Linux fs is mounted on sda7.
some forums online suggested looking at /etc/fstab:
/etc/fstab
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda7 during installation
UUID=fad802b2-f40c-4a8d-93de-128447fc6cd1 / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/sda2 during installation

# swap was on /dev/sda6 during installation
UUID=401c4f54-6932-4987-a9e2-9855a88ce52f none swap sw 0 0
the following is an output of sudo hdparm -i /dev/sda7:

If there is anything else that is relevant, I'd like to know, and thanks for any help.
Small problem with that line of thinking, though it is understandable, multitasking is smooth, unless there is a write IO operation, and the same is true for just running a single tab firefox or LyX (latex editor), so it's probably not ram usage.
For this reason i disabled anything that might do writes in the background except for timeshift, and i saw massive improvements in responsiveness.
Thanks for your input, still.
I have a suspicion my machine might be waiting when it has write IO operations, because it doesn't heat up or make any noise, I've been looking for a way to make a fake io operation or something like that, to confirm this.
