Which feature does Akamai provide to help optimize website performance?

Akamai offers various features to enhance website performance, with one of the most impactful being image optimization and script minification. This feature plays a crucial role in reducing the overall load time of web pages, which directly affects user experience and engagement metrics.

Image optimization involves adjusting image formats, sizes, and resolutions to ensure that they load quickly without sacrificing quality. By serving appropriately sized images for different devices, Akamai reduces bandwidth consumption and speeds up page rendering. Similarly, script minification reduces the size of JavaScript and CSS files by removing unnecessary characters, such as whitespace, comments, and formatting. This smaller file size allows for faster downloads and quicker execution in browsers.

In contrast, while server clustering can improve reliability and failover, it does not necessarily enhance performance in the same way that optimized images and scripts can. Content delivery through virtual private networks is more focused on secure data transmission than on optimizing performance directly. User relationship management, although valuable for customer interactions and data tracking, does not play a role in the technical optimization of website speed or performance metrics.

Thus, image optimization and script minification are central features offered by Akamai to improve website performance significantly.
