True. The guide is an interesting read. When you are deep in the trenches, most of what the github link says is just common sense.

Eg: < Optimize for the slowest resources first (network, disk, memory, CPU) in that order, after compensating for the frequency of usage, because faster resources may be used many times more. For example, a memory cache miss may be as expensive as a disk fsync, if it happens many times more.>

This is just obvious common sense. Great read.
