New Web Accelerator Tutorials Published

We have just published some new tutorials to get you up and running with the latest features of the Sevenval Web Accelerator (WA). The tutorials look at how to use WA for image optimization, content optimization, and request reduction. If you are new to WA, or if you simply want a general, hands-on overview of its most common features, then these tutorials are for you!

The Sevenval Web Accelerator can give your website a serious performance boost, without having to make any code changes to your website. It achieves this as a device-aware, caching and optimizing proxy server that sits between your website and your visitors. All you need to do is specify which features you want to enable in a small configuration file. WA will do the rest, serving up the best optimization possible depending on the user’s device. If you want, it’s possible to have really fine-grained control over the optimization process, on a per-page and even a per-tag level, but that’s not for everyone. If you want to just get it set up and running with minimal fuss, then this is possible too.

In writing the new tutorials, we wanted to give a good overview of the capabilities of WA, without jumping into too much detail. It was also important to us that the performance improvements at each step be documented in a transparent way, with well known and recognized free-to-use tools.

First we set up a new, dedicated example site ( to run the Web Accelerator against. So, you can follow along the tutorials using this test website and verify the numbers for yourself, or you can plug in your own website directly and see how your own website performance improves. In either case, the tools we used to highlight optimizations are ones that are free and accessible to all:

New test website

Chrome Developer Tools showing image size improvements

PageSpeed Insights before and after scores

The tutorials are divided into three sections:

While the tutorial gives a brief description of how to configure the most common Web Accelerator features, many of these features are extremely powerful, and are backed up by detailed documentation should you want to fine-tune them even further.

If you activate all of the features described, you should see handsome performance gains. For our test site, we saw the page size drop from 1.3MB and 24 HTTP requests, to just 169KB and 12 requests. The PageSpeed Insights score saw a radical improvement, rising from 49 to 94! The improvements are documented below!

So what is the impact of all these improvements? First, a much better user-experience: pages load faster, and users don’t need to watch progress bars and spinners. But it’s not just speed! If your site is slow, you impose a real, measurable, financial penalty on your visitors. Looking at the cost per page view of our example site was ~$0.14.

If a user visits the site daily for even just a single page view, this would cost $4.2/month. For a site with 500K monthly users, the collective cost would be $2.1M!

The Sevenval Web Accelerator reduced the payload of our test site to just 12% of the original. This corresponds to a $0.017 cost per page, or $0.5/month. This is an almost-tenfold saving per page! Scaling things up, the collective cost savings for all users would be ~$1.8M. With WA, everybody wins!
