Droplet with blogging platform Ghost consumes 290+ MB of Ram out of available 512. Is this normal?

Question

ubuntu

Greetings!
Please help me with the following problem: Created a Droplet on DigitalOcean with Ubuntu 14.04 x64 (vmlinuz-3.13.0-43-generic) and Ghost blogging platform preinstalled. Chose the $5 package which is with 512MB Ram. I didn’t set anything else, and after a certain time I notice that my appetite begins to grow to such sizes:

Tell me, please, is this normal? If not, how to overcome? On the web, on the official Ghost forum and in the DigitalOcean community, I found references to what is normal for such a droplet in the region of 90 MB Ram.

Answer 1

Change x64 to x86 to start

Answer 2

Very strange, to be honest. In the community, everyone writes correctly: eats 90-120 mb. In a completely similar configuration (the same DigitalOcean, the same ubnta, etc.), I have two installations of Ghost running on one five-dollar instance.
Perhaps the problem is not in x32/x64, but somewhere specifically in this installation.
