Note that if you resize memory you should increase the database memory settings in app.yml as well so Postgres can make better use of the additional memory. And increase the unicorn worker count in the same place so more requests can be handled concurrently.

I followed this instruction discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub

If you are using a 1 GB instance, set UNICORN_WORKERS to 2 and db_shared_buffers to 128MB so you have more memory room.

if I use 2GB instance, should I increase UNICORN_WORKERS to 4 and db_shared_buffers to 256MB?
