aside: with the current lock-free architecture, CPU cycles for a multithreaded constant workload are pretty variable. this is probably only stable enough for low error readings in single-threaded workloads.

some good ideas from https://www.sqlite.org/cpu.html regarding repeatability: wall time is not repeatable, but the number of cpu cycles required to run a workload will be far more stable.
with this in mind, we should create a script that breaks down operations by cpu cycles for a standardized workload
