How many sites can withstand my droplet?
I have droplet (10$/mon) with CentOS 6.5 64bit. Installed vestacp with apache, mysql, php, assasin spam filter, webmail roundcube. In this droplet now working 2 modx sites, 2 wordpress sites. All sites have a low load. Quesion is: how many sites I can store in this droplet for propely working (approximatly)? Now free memory is 160mb (is it normal?).
I suspect that I setted up my system not correctly. I'm newbie in this.
