In order to run a business online, your website needs to be fast to serve the users. Website speed is an impression that will be considered by the users and even developers and testers who build it. High-performing websites result in various positive factors including more visits, low bounce rates, engagement, and high ranking.
The below-mentioned techniques help developers to build websites that will be more effective and fast on runtime.
1. Use Content Delivery Network (CDN):
A Content delivery network is a location-based web server that provides the user with web content based on the user's location. Generally, there will be many servers, the web content is shared with the user from the nearest server of the CDN which makes the content delivered within a short time.
2. Image Optimization & Compression:
Scale your images which can be accessed easily, If possible make the images and other files capable. Large images in the server may slow down the website performance when multiple users request the resources which are shared across multiple users at the same time.
Large images can be compressed and optimized for better website performance.
There are many tools available in the market to do so. They are listed below:

You can use the below .htaccess code to server your images with the WebP format:
RewriteEngine On RewriteCond %{HTTP_ACCEPT} image/webp RewriteCond %{DOCUMENT_ROOT}/$1.webp -f RewriteRule ^(path/to/your/images.+)\.(jpe?g|png)$ $1.webp [T=image/webp,E=accept:1] Header append Vary Accept env=REDIRECT_accept AddType image/webp .webp
3. Database Optimization & Performance:
To serve the dynamic web content for large user groups, database optimization and architecture play a key role in the website performance. The more the database scalability the high the website performance.
The database should be designed in such a way that the rows in the tables should be fetched within less time by using indexes and temporary tables.
There are various concepts including performance tuning, Indexing, Buffering, and Caching that are available for the modern database resulting in better database optimization.
4. Minimize the HTTP Requests:
The HTTP requests should be minimized so that each time when user requests there will be less number of requests associated and the server may respond quickly to handle it and will be ready to process a new request. Heavy requests may keep the server busy and will decrease the performance of the website.
5. Hosting:
Choose a better hosting provider with hardware, the more hardware and intensity of the hosting server, the website performance will be increased.
Choose dedicated servers for the hosting which are not shared with other servers.
6. Javascript and CSS Minification:
Minimizing the js and CSS files will increase your website speed because if they are minified the file sizes and content will be reduced and minified. the un-minified CSS and js files take more time when loading a page as the page needs CSS and js files for sure.
