Is this the only thing running within the VM?

What’s the result of `cat /proc/meminfo | grep MemFree` ?

Did you follow the [Standard Install](https://meta.discourse.org/t/142537?silent=true) and run `discourse-setup`? It should tune the memory settings for the spec of the VM assuming it meets the minimum requirements.

What are `db_shared_buffers`, `unicorn_workers` and `db_work_mem` in your app.yml?
