Regular readers of this blog will be aware that here at Trust IV, we’re passionate about web performance. If we spot a poorly performing website, it makes our blood boil. We know that there is rarely a good excuse for poor performance (provided that you know where to look for bottlenecks).
Performance bottlenecks often become apparent only under heavy user load, which explains the need for thorough application performance testing. Occasionally though, websites perform badly for more obvious reasons, such as not compressing or caching content, not using a CDN or simply using large images (or too many images) on a page.
To help visualise the reason for these types of performance problems, it can be useful to use tools such as YSLOW or Google PageSpeed to look for these bottlenecks. There are also a number of online tools that help you do this. One of my personal favourites is WebPageTest which uses agents installed on PCs and servers all around the world which measure your site’s performance using real browsers such as IE, Chrome or Firefox.
WebPageTest allows you to run simple tests or perform more advanced testing including multi-step transactions, video capture, content blocking and much more. The information from each test provides useful diagnostic information including resource loading waterfall charts, PageSpeed reports and suggestions for improvements.
Trust IV is pleased to announce that as a result of our partnership with WebPageTest, it is now possible to measure the response time of your website from our data centre in Manchester. To do this, visit WebPageTest and choose “Manchester, UK” from the Test Location dropdown. This allows you to measure the performance of your site using IE9 or the latest versions of Chrome or Firefox.
For more regular tests or a competitive analysis of your site against the competition, get in touch and ask us about our performance monitoring and testing services.
