Can't believe this bug dates all the way back from 2014 and 8 years
later in 2022 this is still a thing! Not only that the bug has nobody
assigned to it and is of "undecided" importance!
My experience is appalling even by juggling with the vm.dirty_ratio and
other dirty bytes values and my system

I still have the but if my Chrome/Chromium and associated 30 tabs have been

Monitor dirty files memory,
Change to more suitable values.
What it does: change from default 10 and 50%.
My understanding:
If `(vm.dirty_background_ratio/100) * memory size > largest file size`, then it
should be ok.[reference needed]
Note: `memory size` may be *available* memory

* Transfer speed from internal SSD to external SSD. (See attached image)

3. The system is really unresponsive
