> 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](https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md)

> 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?
