I started an ec2 instance (micro) to test the amount of memory I have available to run a website but I was expecting having a bit more. So my question would be: How much RAM do I need to run a site using Django, Nginx and Gunicorn. This is what I found:
Starting a Ubuntu 12.04 instance consumes:
total used free shared buffers cached
Mem: 590 235 354 0 7 182
-/+ buffers/cache: 45 544
Swap: 0 0 0
After running Gunicorn:
total used free shared buffers cached
Mem: 590 195 394 0 9 73
-/+ buffers/cache: 112 477
Swap: 0 0 0
So I have 394MB available although I forgot to create a swap volume. Is that enough to run a forum receiving 3000-4000 visits per month? I would also appreciate some comments on the proper way to configure swap.
Thanks a lot
