Here is TOP in CentOS 7 for my Apache Wordpress server. I set swappiness to 10. I gave it 12 GB of ram. Why is KiB Swap used so heavily? I was considering reducing RAM to 4-6GB since it won't use it.

It seems to be the KiB Swap = 0 used

Is this what you're referring to?
Is this running in a VM? That could skew the information you're seeing.

I misread that line completely. With everything crushed together on the TOP screen. WOW! I must be more tired than I thought. Thanks. I can reduce the RAM down from 12GB since it is not even using 1 GB of it.
