Lag on Vbulletin website

[محروم.كوم]

My website is experiencing a lag on the opening of each page. The server says it is not on their end. Is there any way to identify the cause of the lag without restoring the site to the original setting and starting from scratch?


Is there a way to load the code line by line to see where the lag comes from?
