One of the things that my most recent job really highlighted was - speed matters, but you need to know how it matters. In my particular niche essentially there were cliffs. If you were faster than x, you got y, if you were faster than x2 you got y2. Basically, you could halve the latency of your system for 0 benefit. You could decrease the latency of your system by 5ns and the benefits would be amazing. You could gain 5ns and it'd be nothing. Speed does matter, but first, you need to know now.
