About two weeks ago my site went from loading pages almost instantly to taking 9+ seconds to load.
I have not added any new plugins, and only one small image (less than 400kb) in the last month.
I cannot figure out why it is running so slowly now.
I already de-activated all the plugins (did not affect site speed). Other items on my server (PDFs) are loading very quickly -- it seems to just be the pages run through wordpress that are slow.
