New Digital Ocean pricing! (Spoiler: $5 for a 1GB droplet)

I’m currently using this package from them with Discourse Version v2.0.0.beta2 +72 / 2.0.0.beta2
DOpackage

And experiencing high memory usage with only me on Discourse:
memoryUsageDiscourse

Any advice on troubleshooting this?

Edit: Upgraded to 4GB Memory and added a 2GB swap file. Memory usage is still around 50% though
