BPF really seems nice. Ramifications to me though are: if I was willing to pay a few percent overhead on all my production instances, what I would be able to monitor 24/7 and get a return on the investment, and I haven't found much writing in that area.
Seems like there could be a lot of opportunity, hopefully I'll get a chance to dive in and find out myself.

Pick the cheapest place to have a bottleneck. Using SSD at an extra 30$ a month lets you use half the CPU and RAM, saving 60$ a month? Go for it.
