There are many factors that may affect your website's loading time. Most of the time, the speed depends on the server that is hosting it. Specifically, it could be due to a MySQL server overload or it could also be that your site had already reached the limit on the number of processes allowed per account. Most shared hosting companies limit the number of processes to 20 to 25 per C-Panel account. This limit could greatly impact your website's performance especially if you are hosting two or more websites on a single hosting account.
