Any way to make Webview faster?

In my app, the Webview is super slow and sluggish. It only happens with my friend and that’s because his internet is not too fast. I have 30+ MBPS internet and on my phone, the webview is slow but better than what my friend experienced. Is there any way to make a Webview faster? Like preloading a page or storing a page somewhere?

Chrome is much faster than my app. Can I make my app faster in some way?
