It was certainly acceptable till the kernel changed something, and swap 
started sending the disk head everywhere. It was very obvious: same 
load, one day, and the day after the upgrade, very slow.

I no longer remember what upgrade it was, and can't locate my mails on 
it. 2017.

It became acceptable again when I replaced the system hard disk with an 
SSD and the swap partition went there.
