EventSystem.Update() lag spike in profiler on first call

From what I have read, the EventSystem only loads on the first call. Is there a way to load it during the splash screen so I do not have a stutter on the first tap/click? Cheers.

In my case, it was a call to DateTime.Now somewhere deep in the methods that was slow!
take a look at this:

I replaced the code with Time.time and it’s fixed now.
