How can we optimize slow loading web sites?
1. Minify all CSS & js files. What is minify? Minification is the process of removing all unnecessary characters from the source codes without changing their functionality. 2. Use optimized images instead of actual size image. What is image optimization? Image optimization is about reducing the file size of your images as much as possible without sacrificing quality so that your page load times remain low. 3. Use Gzip compression. What is gzip compress? Gzip is a method of compressing files. Compression allows your webserver to provide smaller file sizes which load faster for your website users. 4. During the image upload perform image resizing so the same image should be generated with multiple sizes that we can use at required positions. 5. SQL Query optimization- for better performance. 6. Enable cache - ( Redis / Memcache / file cache as cache driver ). For enabling browser level cache you can use IndexDb with expiry time& Cache-Control with
