I have a 1GB VPS server. I setup 1GB of swap ram too a few weeks ago and quite often it's hitting 99% whilst the regular memory is usually 40% - 60%.
Most of my sites on the server run fine and fast. But the wordpress website I am developing is very slow. It's not public yet so even when I am on the backend updating a post for example it's slow, on the front end it's slow too etc.
I'm working on removing the plugins to try see what may improve if any but I think this is just building up overtime it seems, wasn't sudden.
Could maybe do with some suggestions on what to SSH and check into etc, what commands to run too. Here is a screenshot from a few minutes ago.
