As promised, here is the chart of a Linux Ubuntu server 24 hours or so after turning off swap (it is still off).
As mentioned, on this server there is plenty of memory (for the applications) so there is zero issue having swap turned off:
I can continue this for a few of my "busy servers", some very busy, but all have plenty of RAM, so all will perform just fine with swap turned off (since they do not really use any swap with it turned on).
Anyway, I don't want to beat this dead horse any longer...
Computer RAM is cheap.... if your system is swapping, buy more RAM.
Cheers.
