Ghost ram usage

Does anyone know the reqs for ghost-cms?
Haven't found anything on google.

128mb should be fine for a basic non busy blog, 256mb to be safe. Assuming nothing else running on the VPS other than the OS.
I found this:
https://ghost.org/forum/using-ghost/5389-best-enviroment/
https://ghost.org/forum/installation/563-ghost-memory-usage/
I'd say 256 MB RAM would be the minimum if you're only going to be running that. Maybe even 512 MB?
I recommend that you get at least a 512MB VPS. On my blog it's currently using more than half of that. It is under KVM not OpenVZ (should use less in OVZ). I had applied Nginx static file caching and some other optimizations.
When I tested (1 ghost blog running with forever and nginx): 2 node processes, 39 M and 19 M when first started. After opening and closing some 20 instances of the front page, adding a few more short posts and refreshing one page about 20 times, memory usage for the first node process went up to 53 M, the other is 20 M. The estimates in the ghost forum threads about 60-70 MB per blog looks about right.
Not sure how well it scales to traffic though, ymmv.
My production Ghost blog runs at 53 MB with 5 threads. I have an API that runs under Node.js using about 10MB with 1 thread. So about 10MB per thread.
I'm using Apache2 as a reverse proxy as well as serving content for my other domains and applications (Mono). It uses around 15MB.
I would say you could run Ghost with a MySQL backend using Nginx in under 256 RAM. I'm using Upstart to manage Ghost so no extra overhead of Supervisor or Forever.
I'm running ghost for erawan.me under 256mb kvm vps with supervisor and some other program.
Tried to run it in a 50mb vps but didn't work.
i host it under 128MB of RAM, and it use about 40% of it
Something not right there, what else you running on the VPS?
ITT: People who do not understand Linux memory usage.
For @W1V_Lee and others interested - on my blog, here's the ram usage statistics in
htopfor all Ghost-related processes:On my OpenVZ VPS with 1GB RAM:
On another KVM VPS with 512MB RAM:
I use Nginx as a reverse proxy, compiled with the ModSecurity module. If you are curious, my Nginx configuration can be found in the Ghost blog tutorial in my sig below.
Hope this helps!
EDIT:
It turns out that some of the "processes" in the original screenshots are just "threads" (press "H" to toggle), whose memory usage should not be counted. I have recaptured the screenshots and NOW they are correct.
512 MB is good enough with a lot of room for growth.
Thanks everyone for the help!
