Sevenval FIT 14.5.2

FIT 14.5.2 is another release bringing mostly bug fixes and improvements for existing features.

Delayed images prioritized to be loaded when they are going to become visible considerably reduce traffic. But if visitors want to print sites, they are basically missing every image that neither is nor has been in the viewport. The new parameter of the loadHQImages function makes the client load all images, whether they are in the viewport or not. And the new event delayedimagesloaded informs you when the client finished doing so. So this combination offers means to prepare the site for printing and lets you know when preparing has finished.

FIT 14.5.1 already addressed noise in the logs. We identified another source for noise, namely overly greedy bots (such as Google spiders) interpreting JavaScript strings starting with a / as relative URLs. So when you write something like <script>var foo = '/bar';</script> into your document, it will not take long until you notice said spiders requesting the resource /bar. This will probably lead to unnecessary 404 responses, inflating the FIT server logs and backend server logs, thus probably hiding real problems from you. FIT 14.5.2 will no longer generate JavaScript strings starting with a /.

Additionaly, fixing issues with the image scaling cache has reduced the CPU usage noticeably.

The SDK for 14.5.2 is available from Github.

FIT 14.3.1: Web Accelerator and RDL Update

Today we have released version 14.3.1 of our FIT software, including updates for the Web Accelerator and Rapid Development Layer

We have learned a lot from analyzing our image traffic. Therefore, this minor release focusses on bug fixes and enhancements of image processing.

Many images are small enough, in terms of dimensions, to fit into current clients’ viewports. That is because many mobile devices have high density displays (e.g. Apple’s retina display) resulting in lots of pixels. Those images don’t need to be scaled. Therefore, Image Scaling and Compression are now separately configurable. This can be useful for CSS documents with image sprites that should not be scaled but still be compressed.

If an image is known to be small enough for the requesting client, FIT will automatically switch from Image Scaling to Image Compression. The latter uses image URLs without sizing parameters, resulting in a better cache hit rate (in FIT and in downstream caches) and reduced disk and CPU usage.

Another finding in our image statistics is that in certain cases image weight (i.e. file size) may be increased by our image processing. Now, the smaller original image will be sent to the client instead of the processed image. We call that pass-on-enlargement. Since animated GIF images are hard to optimize and are practically never scaled, they are no longer processed at all.

We have further improved SVG as a replacement for transparent PNGs (also known as “zorro”). The alpha map is smaller. And a bug showing artifacts at image borders was fixed.

Developers will find some interesting enhancements, too. The content DC properties for example let you run Flow actions depending on the type of content (e.g. html or js). The detection page can now be disabled on a per-URL basis.

The SDK for 14.3.1 is available from Github.

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
