When it comes to site optimization, our theme plays a much smaller part than you might imagine. Xhibiter is optimized so that it’s fast on its own, but ultimately, content will primarily dictate how fast your site will perform. Images play a huge factor in speed results, as well as hosting, server, extra plugins, content and more.
Images
First and simple rule: Don’t upload larger images than what is needed. We recommend 1920 x 1080 as a maximum resolution for your images. Crop your images and optimize them with tools such as Optimizilla. It can reduce image size up to 90%.

Caching / Minification Plugins
We recommend using these caching plugins. However, depending on your server configuration they can work differently.
Hosting
If your site hosted on shared hosting, consider upgrading to a better hosting plan or get a VPN. Some shared hosting services can be overcrowded and have a direct effect on speed. Hosting can play very big role in your site speed. On our demos we’re using Cloudways, which has good speed performance and starts from $10 a month.
Gzip Compression
It can dramatically reduce file sizes ( upto 80% ) of static files like html, css and javascript during delivery. If your web host isn’t doing this already, please contact them and setup gzip compression. Plugins like W3 Total cache and WP Super Cache have options for enabling gzip compression.
