I am running a 1GB DreamHost VPS right now for a single website. The VPS Optimization Wiki states that “Every DreamHost virtual private server (PS) uses roughly 100 MB of memory as a baseline without any user processes running.”. Does that mean that 100MB of my 1GB VPS will be unusable? if so then should I allocate only 900MB in my phprc file for my website?
I’m also using NGINX as my web server right now. I noticed that it uses a lot more RAM when compared to Apache. I barely get any site visitors right now, but my RAM usage hovers around 400MB-500MB. Is this normal or is it a sign of a memory leak?
Also, are there any plans to upgrade NGINX in the future? Wikipedia says that my current NGINX version 1.4.4 is outdated and I’m not sure whether this is a big security risk that I should worry about or not.
