Difference in Simulation speed between 2 robots

Hello,

I am simulating a multi robot cell, and the robots are simulating at different speeds. They are programed at the same speed.
I have already confirmed the controllers for each are reading 100%.
The simulation is set at 100% in the simulation settings.
Where else can I control simulation speeds?

how big is the difference and which robots are you using?

Are the robots of the same specs? In other words, the same type of robot with the same reach?

Are the two robot using the same load data and tool data ?

Any velsets or accsets in programs? Also, any arm load?
