Clean your Media Library and your Uploads directory from the files which aren’t used.
I recommend strongly using an excellent and recognized hosting service. My first recommendation is WPEngine:
They include security, performance and a lot of tooling. If you can’t spend as much, then SiteGround is the best second alternative. They less tooling and security but the performance is as good.
All my plugins are tested all the time with those two hosting services. Last but not least, I recommend you using Cloudflare (the free version) for your DNS and Fastly as a CDN for both for your content and static resources. It’s free if you don’t run a huge website; simply mention them when you create an account that you are using plugins made by Jordy Meow from Meow Apps.
