Feels like this would be a good candidate for Pike's programming rules (
https://www.cs.unc.edu/~stotts/COMP590-059-f24/robsrules.htm...):
"Rule 1. You can't tell where a program is going to spend its time. Bottlenecks occur in surprising places, so don't try to second guess and put in a speed hack until you've proven that's where the bottleneck is.
Rule 2. Measure. Don't tune for speed until you've measured, and even then don't unless one part of the code overwhelms the rest."
