Swap file size

Is it normal have swapfile 7.4 GiB bigger than any other file whole server?

I had too one site with 8 GiB js cache file created by litespeed cache plugin…

I don’t know much about swap, but it seems to me that it would be ideal if swap was never used at all… I’d check your memory and swap configurations. You’ll have tos search the net for specifics though
