Caching plugins performance can vary per Hosting. Some will perform better on your server than others. You have to install them and see which performs better.
Try: http://gtmetrix.com/
I think your redirect at Server level might be a Cpanel redirect. A Pure .htaccess redirect to https might be faster. Find out from your Host how they did the redirect.
Check out your ‘Timeline” in Gtmetrix and you can see that your site is “waiting” for 1.5-2 seconds. Your DNS lookup is a little high too.
Open a Ticket with your Host to see if they have any suggestions.
