Cyberpanel/Openlitepseed is not utilising CPU & other resources

Cyberpanel/openlitepseed is not utilising high load by using the cpu/compute power. As you can see it uses only 10-20% of cpu.

Meanwhile if my website get high traffic it slows down, instead of using the cpu or other system resources such as i/o and port speed. The system resources and compute power is not being utilised well.

Is there anything I can do to optimise litespeed or php through tuning?

I guess it will need to be tuned a little bit more. Any experts suggestions will be appreciated! :slightly_smiling_face:
