What are some of the points to elevate theme performance when purchasing from theme forest

I have a question regarding evaluating the performance of the theme listed under ThemeForest marketplace. How can I judge the theme will load faster and will not become slow as the site grows.

By getting better/faster hosting service would be a start.

As @ki-themes says - decent hosting is prob where to begin but also -

  • do you know how to minify code and scripts

  • how much of the complete demo are you actually going to need to use and can you remove what you don’t need

  • don’t forget to optimise your assets

  • don’t further bloat things with plugin overload

It also depends slightly on the theme but it’s important to remember that demos contain everything and far more than you are actually going to need
