[UIProfiler]Time ms increases for Profiler.FinalizeAndSendFrame when the Profiler is open



To reproduce:

1. Create a new project
2. Add many different UI game objects
3. Enter Play mode
4. Open Profiler
5. Wait for a few minutes
6. Observe how much time the Profiler.FinalizeAndSendFrame method takes

Expected: Profiler.FinalizeAndSendFrame doesn't have so much overhead

    +1. On 2017.1.0f3, triggering when the window is full of samples and goes back to behaving when I hit clear.

    Same thing here on 2017.1.0f3. I don't know if the repro steps are the same, and I'm not sure it's directly related to UI, but once the graph fills up then FinalizeAndSendFrame time goes nuts.

    Same here. Version 2017.1.0p4 Personal.
    Profiler.FinalizaAndSendFrame takes 3-4 ms max after pressing clear, but as soon as the graph fills up the profiler area it goes up to at least 20ms. It was higher than that before I had tried clearing it.

    Same here - pretty grim. Closing the Profiler tab fixed the issue.

    So not many people are experiencing this? just 9 votes? What are we doing wrong in comparison.

    Seeing the same thing. Ever since installing 2017 I was noticing the framerate just tanked in my project. Turns out the profiler itself, while active, is chugging really badly.

    When I press clear button, temporarily the fps is fine but after more than 1 sample, the situation is same. very annoying.

    It seems related to the profiler having more samples than it can show.

    In that short clip you can see that it starts the moment it's filled up the window with samples. It disappears the moment I press clear.
