Very slow home page in backoffice

[Fer5320]

For a few weeks now, the backoffice home page has been taking a long time to load. Each day that passes adds about two seconds more than it takes to load. I always have many bots connected, but I tried blocking them and it was still just as slow loading, so, in principle, the problem does not seem to be there. The rest of the backoffice works normal and is not slow, except for the click upgrade module, where the spinner does not stop spinning as it does not finish loading something. Any ideas?

Thanks
