Increasing FPS

[josemendez]

what do you suggest for me?

This is a classic case of death spiralling: physics are being updated 6 times per frame, as indicated in the "Calls" column of the profiler. They should only be updated once.
Reduce Unity's max fixed timestep in the Time manager. See:

https://docs.unity3d.com/Manual/class-TimeManager.html

Also, check if there's something being written to your console. +6000 GCAlloc calls in EndStep() suggest that something is being logged, and logging is both slow and allocates memory.
