Hello,

We are glad that you have found a solution to one of your issues by yourself.

2) In general, our theme is already optimized and doesn’t have too many resources to make your website slow. Most likely, your website performance suffers from the content you have added to your website. It may happen in case of too many plugins, large not optimized images or other resources. So we suggest you to remove unnecessary plugins, install some kind of JS & CSS optimizing plugins like Better WordPress Minify and a caching plugin like WP Super Cache. Also, you can use GTmetrix tool to see what makes your website slow and optimize these parts of your website.

And the AJAX searching speed depends more on your site’s server settings and capabilities, rather from search source code or our theme.

Best Regards.
