There are several things you can do to speed up your WordPress website:
Compress and resize images to reduce their file size, which will speed up the loading time of your website.
Use a caching plugin. It stores frequently accessed data on the user's computer or server, which reduces the number of requests made to your server and speeds up the loading time of your website.
Minimize plugins. Too many plugins can slow down your website, so use only essential plugins optimized for speed.
Choose a hosting provider that offers fast server speed, optimized servers for WordPress, and CDN to speed up the loading time of your website.
Choose a lightweight theme optimized for speed, and avoid using bloated themes with unnecessary features and functionalities.
Minimize the number of HTTP requests made to your server by reducing the size of CSS and JavaScript files and combining multiple files.
