Server response time is the time taken for a user’s browser to receive a response to a request made to the server. According to Google PageSpeed Insights, server response time should be less than 200 ms. High response time results in slow loading of the website, decreased SEO performance, and a negative impact on user experience. In this article, we will discuss the best optimization techniques that can be applied to reduce server response time in detail.
1. Improving Server Performance
1.1 Choose a Faster Hosting
The server hosting your website is the most significant factor affecting response time. In shared hosting, performance can decline because you share the same server with hundreds of different websites. Better options:
VPS (Virtual Private Server): Better performance with fewer shared resources.
Dedicated Server: A server assigned exclusively for your website.
Cloud Hosting: Offers scalable and fast solutions with dynamic resource management. If you want to minimize server response time and maximize your website's performance, you can check the High Performance and Reliable Infrastructure Solutions with PlusClouds section at the end of the article!
1.2 Optimize Server Location
The further the server is, the longer the response time. It is essential to prefer servers that are closest to the region where your target audience is located.
1.3 Use HTTP/2 or HTTP/3
The next-generation HTTP/2 and HTTP/3 protocols significantly reduce server response time by offering faster connections and parallel data transfer.
2. Database Optimization
2.1 Clean Up Unnecessary Data
Unnecessary or outdated data can extend query times. You can optimize your database by using the following methods:
- Delete unused tables.
- Clean up duplicate data.
- Perform archiving operations for large databases.
2.2 Optimize Database Queries
Complex and heavy SQL queries can increase server response time. Instead:
- Reduce unnecessary JOIN operations.
- Use INDEX to ensure queries run faster.
- Use caching to prevent frequently used queries from being reprocessed.
3. Using Caching
Caching greatly shortens response times by reducing server load. The most effective methods are:
3.1 Server-Side Caching
Allows the server to temporarily store certain pages or data. For example:
Opcode Cache: Reduces processing time by caching dynamic languages like PHP.
Redis and Memcached: Used to speed up database queries and dynamic content.
3.2 Browser Caching
Allows static files (CSS, JS, images) to be stored by the browser. Can be configured using Expires and Cache-Control headers.
3.3 Using CDN (Content Delivery Network)
CDNs cache content on geographically distributed servers and deliver it from the server closest to the user. Popular CDN providers include:
- Cloudflare
- Amazon CloudFront
- Akamai
4. Server and Application Layer Optimization
4.1 Compression with Gzip or Brotli
Text-based files like HTML, CSS, and JavaScript can be compressed using Gzip or Brotli. This reduces file size and decreases server response time.
4.2 Remove Unnecessary Plugins and Modules
Especially in CMSs like WordPress, unnecessary plugins can cause additional server load.
4.3 Use Keep-Alive and Connection Pooling
-
Keep-Alive: Maintains a continuous connection between the server and the client, eliminating the need to establish a new connection for each request.
-
Connection Pooling: Reduces unnecessary load by allowing database connections to be reused.
4.4 Update PHP and MySQL
Newer versions contain performance improvements. For instance, the PHP 8.x series is much faster than previous versions.
5. Content and Media Optimization
5.1 Image Optimization
Images are one of the largest file types on websites. The best optimization methods include:
- Use WebP format.
- Enable Lazy Load for images so they load as the page is scrolled.
- Compress using tools like TinyPNG or ImageOptim.
5.2 JavaScript and CSS Optimization
- Remove unused CSS and JavaScript code.
- Delay the loading of JS files using async and defer.
- Compress CSS files to reduce their size.
5.3 Minify HTML and CSS
You can ensure HTML and CSS files load faster by removing unnecessary whitespace and comments. Minify tools include:
- HTMLMinifier
- CSSNano
- UglifyJS
