Slow site

Slowness/high CPU usage could be due to (but not limited to):
– A poor or memory intensive theme. Switch to the WordPress default theme and test loading time and see if you see a difference. If you do, may be your theme can be re-written to be more efficient.
– Poor or memory intensive plugins. One by one disable plugins and test loading time and see if you see a difference. If you do, may be that plugin can be re-written to be more efficient.
– your server is slow (e.g., “process hang”, overload, you get a lot of visitors, other problems, etc.); generally, every inexpensive host out there is slow.
– lots of images.

Could you please provide a list of plugins you are using?
Here is a report from GTMetrix.

Based on the report, here are my recommendations.
A: Install W3 Total Cache. Enable caching, minify, browser cache, and CDN if you have one.

B: Get a CDN: This will help host all those images you got.
https://maxcdn.com
C: Install a plugin Speed Booster Pack. You should enable Move scripts to footer, Defer Parsing of Javascript files, Remove Query strings, Lazy load images, Change the compression level to 60, Load CSS Async, Minify all CSS Styles, and that is it.

D: Install EWWW Image Optimizer to compress some of those images.

E: Use Gzip: Add this to your Apache .htaccess file.
