heh, try using Windows when it goes into swap, Windows both desktop and server additions have the worst memory management I've ever seen and having no ZRAM and a pig of a filesystem like NTFS really doesn't help either.

Going into swap in Linux isn't a problem, it's a symtom of a misconfigured / provisioned server or an unhanled application memory leak, other than that the other only things that should cause it is incorrectly configured use of shared / reserved memory.

Disk based swap should pretty much always be disabled these days and ZRAM used to incresed efficiency.
