Hello,
My Mysql uses too much CPU (130%).

7.12 (1 min) 7.20 (5 mins) 7.51 (15 mins)

and sometime higher than these values.

is there any way to optimize Mysql to decrease this load?

Thanks

Not entirely sure about how to lower the load, but here are some suggestions from the library for Memory.

The number one thing is to make sure that your database schema is efficient and correctly indexed. Indexing can make orders of magnitude improvements in performance, depending on table sizes.
