Yes, I double-checked it's a pseudo-probed binary not dwarf-correlation. Note that for end to end test, the pseudo-probe decoding is not the bottleneck(only account for < 1% run time), so neutral for run time is kind of expected. I was to test if the Address2ProbesMap `find` could regress the run time.
