Rewired - Advanced Input for Unity

This is only my speculation so far, but just wanted to get some opinion on performance difference between Mono and IL2CPP build on Windows while using Rewired.

My project runs slightly slower using IL2CPP than Mono while using Rewired, and I want to find out if there is any particular reason for this. My game is turn based game, so most of the time, the game is just sitting and doing just rendering and waiting for an input. My initial search result in the Unity being slow on interface calls, so I was wondering if Rewired gets hampered by such “issue” from IL2CPP virtual call issue.

Any idea?
