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. -- Cheers, Carlos.
