Mo’ Speed – 25% faster Web Accelerator in FIT 14.3

This update brings a significant performance boost to the server-side! The overall CPU usage is reduced by 25% on average. Depending on the features in use, sites may see even larger savings in CPU time. This is not only a benefit in terms of hardware savings. Since the responses are generated more quickly, resulting in shorter times-to-first-byte, it can be a major improvement to your site’s critical render path. These performance gains result from the update of the underlying PHP engine to the much acclaimed version PHP7.

The Web Accelerator was improved, too. As images are a very important part of the user experience, support for WebP and SVG images is now determined automatically by the client feature detection. Before 14.3, these capabilities were taken from our Client Description Repository. With the new on-the-fly detection we have more accurate information when dealing with new, unknown clients. FIT now uses URL encoding instead of base64 when inlining SVG images, which results in more efficient transfer compression and a reduced payload for the client.

The documentation now has a section on beta features. It offers an overview of experimental features that we make available for pre-production use. Any developer feedback on these features is highly appreciated!

With this major release, we introduce support for OpenSUSE Leap 42.1. We have also removed some formerly deprecated features. Please note that Session Management and the Load Brake have been removed. Support for

The SDK for 14.3 is available from Github.
