Ignore that comment from GMetrix imo.
Are you redirecting the site at the server level ?

You have other issues to address before any redirects :

The site prints 389 lines of markup before it even hits any content.

thanks for your response! The hosting is supposed to have corrected this. I am waiting for the server cache refresh.

Can you pinpoint me which thing I should take care of urgently please? I have been adjusting many thing and the site is still very slow…..

thanks!
