Is the performance of this emitter normal? (Niagara)

This is my first particle system. That’s why this question may seem very newbie…

The thing is that when looking at the performance of the emitter I see that there are some things that seem to be too high.

I have tried to modify the configuration to see if that way I get better performance but I can’t reduce the percentage.

Here some screenshots:

Is it normal to have those values or is there something that can be done to get better performance?

NOTE:
I will share the file for you if you think it is necessary. No problem!!

Thank you so much!!
