At what point should I consider increasing RAM on the VPS hosting my Discourse instance?

Right now I have it running on a VPS at 2GB RAM. For the last week, I see it sitting between 70-100% utilization. Thoughts on when to push to more RAM?


That RAM consumption is perfectly normal to me.
Generally, Iā€™d upgrade resources when at least two of the following conditions are met:

  1. I Have a significantly higher number of users now
  2. My forum goes very laggy as soon as my users start participation in discussion
  3. My Host (VPS) is regularly crashing or going OOM or my service provider is nagging me about resources.

Higher utilisation of resources is a good sign while slowdowns are the first signs of real problem.
