How would you design a debugging strategy for nondeterministic performance in Julia?

You isolate sources of nondeterminism like GC, threading, caching, and JIT compilation effects.

Nondeterministic performance often comes from garbage collection timing, thread scheduling, cache effects, or JIT compilation variability. Debugging requires controlled environments, repeated benchmarks, and disabling or isolating subsystems. BenchmarkTools.jl helps reduce noise.
