After latest update site loading significantly lower
I cloned my real live site (https://tinyurl.com/2s3e8tjv) with updraftclone (https://v670wzwxl71.c.updraftclone.com/) to check Theme, Wordpress and plugins updates and errors. Fortunately everything seemed to work, but noticed significant slow site. At first, I thought it was the clone server, and I made the same updates on the live site. I cleaned the cache and noticed it is indeed extremely slow, so It must be related to the new update somehow. I tried to turn off plugins one by one, but so far did not fix that and turned back to the old theme, which is fast.
What to do or were to look for? If you need access let me know - clone or live.
