we have a dedicated server, which host 4 different sites, with very low traffic. we have a new site there which has no visitor traffic yet.
the new site uses prestashop platform, runs on php, mysql.
The server response time and time to first byte for this website is very slow. The other sites on the same server are working very fast. However this new site is working very slow.
The website page score on Gtmetrix is 82% but the page load time is very slow between 6 to 9 seconds. The main reason the server response time and time to first byte.
So we are looking for someone skilled who can help make our website load faster. We want the entire site to load under 2 seconds.
