<b>Ditch disk swap, use zram</b>
Just did this on a $5 box: stopped thrashing the SSD and got compressed RAM instead.
— <code>apt install zram-tools</code>
— set <code>ALGO=zstd</code> and <code>PERCENT=50</code> in <code>/etc/default/zramswap</code>
— <code>systemctl restart zramswap</code>
Now 1GB of "swap" lives in RAM, zstd-compressed ~3:1. PHP-FPM spikes stopped killing me and disk wear dropped to nothing. Keep a tiny 512MB disk swap as a backstop at low priority. Try it tonight.
