Looking for help with listingpro theme

I am using listingpro theme for https://www.imexdb.com
It has a performance issues. It has 14000 listing but website is consuming lots of RAM on my web server.
Server is already optimized for best performance but still website has heavy load.
Hosting company suggested to get help from professional wordpress developer experienced with listingpro theme.
Send me message if you can resolve this issue.

Problem is definitely in your hosting. I can not load a site with any speed test.

ListingPro is not updating the map.

Also how can I add the custom fields like, author name, city, state, zip etc.
