Originally I had run one discourse forum on the 8GB ram, 4core CPUs server.
So the values of db\_shared\_buffers and UNICORN\_WORKERS in the auto-generated app.yml were:
```
db_shared_buffers: "1792MB"
UNICORN_WORKERS: 8
```
Now I have three discourse forums running on the same 8GB ram, 4core CPUs server.
Should I change the value of db\_shared\_buffers and UNICORN\_WORKERS to divided by three?

Your can leave the `db_shared_buffers`… Wait. Are these full app.yml each with their own database server? If so, you really want to run a single postgres.
But if it’s working, you might wait until you have an actual problem.

Thank you.
I’ll try to run a single database.
