You have several problems. The biggest concern is that the default Twenty Fourteen theme has been modified so any future updates will overwrite it. Standard practice is to use a child theme. The lack of a child theme isn’t causing your issues but the edits themselves are horrendous.
You should start by fixing the DOCTYPE declaration in your header.php file. It needs to be the very first entry after the opening PHP tag. After that you may want to run your URL through here and work your way through the errors:

Hope that helps.

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.
