Help make my website faster. (Social engine)

ABOUT: Need someone to go over all my codes and settings to deliver a faster website. *See the photo. TERMS: The project is paid in full once everything is completed to our standards. You must do the changes in a non-production server before doing it on the live server. The files/codes you use/change must be noted in detail so that we can see what was changed in case the file(s) were ever changed in the future. We would know how to fix it back. *If you bid a certain amount and I accept your offer you can NOT change it later, plz read before bidding.
