Over a decade ago, the big bottlenecks for web performance were server load and network bandwidth. Lots of companies sprung up in the Web 1.0 era to help resolve these problems. The most well known and most successful one of course being Akamai. With the creation of CDNs and the use of edge caching, and today with the cloud and especially the ability to scale the number of servers on demand, we solved these two big issues. Companies like Keynote and Gomez built out tools and networks that allowed sites to monitor the performance of their servers from all over the world. Web performance was a solved problem.
Or so we thought. The Web has changed. Performance is no longer a server side issue. It’s a client side issue! As our sites become richer, and especially as they become applications rather than pages, the time it takes for the code to parse, render, and execute the code in the browser has today become the dominant factor in web performance. The time it takes to lookup the domain, connect, transfer the data is now only a small fraction of the overall time it takes for a page to finish loading and be ready for the user to view and interact with.
Till today this was just a theory. It was a theory because all we had available were spot checks of client side performance with browser add-ons like YSlow. Today, that theory now has real data to support it because Torbit has launched Insight. Torbit Insight lets you identify if you have a performance problem on your site and it also lets you pinpoint where that problem may be coming from.

If that wasn’t enough Torbit lets you tie in your site’s conversion rate to show what impact speed has on the bottom-line.
