EventSystem.Update performance overhead

Unity Engine
1

Hello,
I have a game that consists of 3 scenes.
when I open the game the menu scene loads.
My issue is that when I am loading the gameplay scene from the menu scene it takes about 7 seconds.

I monitored the performance with the unity profiler and found that 90%+ of the overhead is caused by EventSystem.Update -

I searched online and couldn’t find any info regarding this issue.
Anyone faced this issue before?

Thanks, Erez

It’s the stuff being called in the Update part of your scripts. You can expand the profiler and see where the biggest offenders are.
