Site very slow after new update

??

Hi Rikard,
Actually I do use third party plugins all of which are reliable and some are premium. I tired options, optimizing and thousands of other things. But especially after the last update my site got significantly slow. I upgraded my hosting plan, deactivated all plugins but still no change. You can find my gtmetrix results. I believe there is something wrong with the updated theme . Maybe it is not compatible with one of the plugins I don’t know. I am generally pleased with the theme and don’t want to change it. But I feel desperate to change it now.

Thanks for the reply Rikard. The case is some weeks ago I wasn’t even aware of web site optimization at all. I didn’t use to do anything to speed my site up. However, after this latest Enfold update my site got really slow. Then I Googled and found sites like GTmetrix and Pingdom. That’s how I learned my site needed some sort of optimizations.
Going back to the issue, my site was working fine without any optimization. Then it suddenly got slower. I changed my hosting plan. It did not work. I optimized my site again it did not work. Maybe it is just a coincidence that I updated Enfold and that it got slow. In fact I need to know what is causing it. Yet. nobody so far have been able to diognose it.

Thanks a million Rikard. Your suggestions helped me look at the right places to sort the problem out.
