My social networking site (php coded), which has only 2 thousand members, is very slow for following:
(i) Slow Login: Members take half a minute to get logged in. I thought I last learned that there are lots of queries run, when members are trying to log in, but yet developer did not think if anyone can be discarded.
(ii) Slow Navigation: Clicking on Search result, or visiting the profile page of any user takes very long for the page to change. This takes half a minute.
(iii) Slow Contact buttons: Clicking on communication buttons like Flirt, Email, takes half a minute.
