I have two Social Engine website. One loads in 20 seconds, the other in 2 seconds. Something is wrong with one of the two sites. It's not the images or content as the site that loads faster is heavier. Something is wrong, possibly a plugin or something. They are hosted on a massive 96 GB ram server with little traffic.
I need you to find the problem and fix it (so that the site loads again in under 3 seconds).
Site speed optimization is already done, that is not what I need. Something is wrong with the site, probably who the code interacts with the database.
