Fresh Wordpress Eating up RAM
I am new here,I just create a new droplet and got a wordpress installed (fresh site/done with serverpilot/ubuntu/Apache), then I went and checked everything, it's already using 3GB RAM, I am on 4GB plan. How's this possible? I am planing to move my 60k pageview/day wordpress site here, but this scared me.
I am now on other VPS on 3GB Ram, but running 5 sites, however only using no more than 2GB ram.
Can anyone explain or help? Thanks in advance.
