For what it helps I am running Node.js with MongoDB and using SSL connection (although the problem seems to persist o non-SSL as well). My initial connection stalls a lot even with basically no meaningful traffic, talking about +10 seconds before the page even connects. Then again, roughly 40% of the time it loads just normally.

Sure I am running the $5 plan, but could that really be a bottleneck already?

My load metrics seem fine, except Memory runs at ~50% and Disk Usage 26%. Not sure if these are normal? Perhaps these are the issues then
