SSL Speed Myth
A prevalent myth among website owners is that using SSL certificates will severely slow down their sites. While SSL encryption does provide an additional layer of protection, it does not have to have an influence on the performance of your website.
Understanding SSL’s Impact on Website Speed
In the past, SSL certificates might have a significant impact on website loading times. However, technological developments and browser optimization have significantly reduced these performance concerns.
Here’s an overview of how SSL can impact website speed:
1. Initial Page Load for website:
- Browser Handshake: When your browser first connects to the server, it goes through a handshake process, which can slightly increase the initial page load time. However, new browsers are well designed to conduct this procedure quickly.
- Certificate Verification: The browser must validate the SSL certificate, which may add a few milliseconds to the loading time. This process is often cached by the browser, making subsequent visits to the same website faster.
2. Content Delivery:
- Encryption and decryption: After the secure connection is established, the data is encrypted and decrypted, which can result in a minor overhead. However, this expense is negligible and frequently mitigated by other performance enhancements.
Optimizing Your Website for Speed
While SSL may have a minor impact on website speed, there are several other aspects that can dramatically impact performance.
To guarantee your website loads quickly and efficiently, consider the following tips:
Image optimization:
- Compress photos to reduce file size while maintaining quality.
- Use acceptable image formats (such as JPEG, PNG, and WebP).
- Lazy-load images, particularly those below the fold, to reduce initial page load time.
Minification:
- Remove any extraneous characters (such as whitespace and comments) from HTML, CSS, and JavaScript files.
- To decrease HTTP requests, combine many files into smaller, more manageable ones.
- Leverage Browser Caching:
- Set the proper cache headers to instruct browsers to save static files locally, lowering server demand and enhancing subsequent page loads.
Optimize the server configuration:
- Configure your web server (e.g., Apache, Nginx) for maximum speed, including tuning options such as worker processes and connection limitations.
- Use a trustworthy content delivery network (CDN) to distribute your website’s content across several servers across the world, lowering latency and improving load times.1
Select a high-quality SSL certificate:
- Choose a reliable SSL certificate vendor and a certificate that provides robust encryption and rapid performance.
- Consider adopting a higher-grade SSL certificate, such as an Extended Validation (EV) certificate, which can give more security and better performance.
