Image resizing. 3. cleaning and optimizing code. 4. Remove unused plugins and replace plugin functions with the theme. 5. Use any of the best cache plugins which is the best for your website. 6. checking webserver like CPU clock speed, ram, configuration, and fixing issues. 7. reducing server response time. 8.
