Every profiling shows twice entries in runs grid. Is frontend “executed” twice?

[drk1]

Hello!

I'm currently doing some bottleneck hunting on my M1. I've installed AOE Profiler. I do some test on category page.

In the backend (System > AOE Profiler) I noticed there is twice entries at every page run (with a delay of ~3 seconds)!

Is that normal (profiling related)? If not, means my performance problems are probably caused by this...

Thank you for your feedback.
