Re: Poor performance of MySQL 5.5

Now the server is very fast.

I installed MySQL 5.6
I turned off query_cache_size.
I turned off HT and NUMA.
I have examined the slow queries and I added a few indexes on some tables that needed them.

The total workload of processors is very low.

I think the problem is resolved.

I thank all those who have spoken in this forum.
Placed below the final configuration, if I can improve anything let me know.
