This has interesting parallels to the issues folks have with autoscaling in AWS. When people first start using autoscaling it can be frustrating finding the right heuristic to scale on, with the automated system over-shooting or under-shooting what the capacity needs are.

What works well is when you calculate your own capacity needs, then just set the autoscaler to change to that new capacity number. In other words, using your knowledge of how your system works, you'll make better decisions than just looking at secondary metrics like resource utilization.

I know I've done manually triggered GC in Ruby and Java but I don't know enough about Go to say if the article's suggestion is reasonable.

What does that mean to calculate capacity needs of the application? Are you saying base it on something like throughput your app can handle?
