@mcruspero, would you be able to share the requests per minute during peak times? You can DM that to me. If you have a lot of users - those are good numbers. But you should still try to keep them below 100ms at all times. This may require a refactor to the DB design and/or adding caching.
In this case, however, the upgrade is advisable - if your app’s codebase and DB design can be improved, upgrade will provide short-term solution; if your app’s codebase and DB design are already at their optimum, the upgrade will help handle growing number of users.
@dilara, I suggest going one step above of what you have currently:
- Standard-2x dynos with double the amount of RAM (1GB) - adds another $25 a month
- Professional tier DB on Standard 0 plan that will allow to have a better insight into expensive queries - adds another $41 a month.
Depending on your subscription and/or contract these can be added free of charge.
