What you did
Attempted to profile many_foxes with trace_tracy enabled. Commented out spans for system_overhead and system_commands.
What went wrong
Profiled measurements for each stage show significant changes. Here's a comparison of the Update stage measurements:

There's only 10-20 systems in that stage, and the overhead scales with the number of systems. This overhead should be much lower, and it makes it difficult to make perf decisions on a macro level.
