Speed is everything when it comes to ecommerce sites, and that's why YSlow has become a go-to tool for measuring site performance.

It's an open source web page analysis application created by Yahoo! Developer Network which grades websites based on their speed and offers suggestions for how to improve them.

When analyzing your website with YSlow, you can expect to receive feedback regarding optimization techniques like browser caching, image optimization, minifying JavaScript and CSS files, using Gzip compression, setting up CDNs, reducing DNS lookups and more. All of these measures help reduce the total number of requests made by the user's browser in order to render a page – thus resulting in faster loading times.

Additionally, YSlow also evaluates other aspects such as how well your server responds or if there are any broken links present on the page.

Using this comprehensive tool provides developers with insight into what needs improvement so they can work efficiently towards making their site faster.

With detailed reports generated after running tests against pages on your website, you can easily identify potential bottlenecks in code that could be slowing down load time and get right back to improving performance.
