since about a week, the site and backend (dashboard) of my WP blog have been extremely slow, it takes ~10 seconds to move from page to page in the dashboard or in the blog. I disabled ALL plugins, but it didn't help. I tried reading in the forums but couldn't find any clear idea what to do. I need some help, how to resolve this issue?
p.s., I went to the PhPAdmin and repaired and optimized the DB, and I am using a paid server host, so I don't think the problem lies there.
