You would need more information from your hosting company on this. As mentioned above, we need to know what is meant by mysql issue. Looking at your system, I am seeing nothing from a software point of view.
It is worth noting that you have quite a few 3rd party applications installed. While they may well not be the cause, it would be sensible to rule those out first of all, by disabling them and testing where you are seeing it to be running slowly. The same would apply to cloudflare. You should remove that from the situation entirely.
If the issue is with items showing a scrollbar for a short time, to looking like they are loading slowly, then you will need to install the optional patch that is showing in the support area of your admin CP.
