Best Practices on Web Performance Optimization (WPO)

Over the last couple of years performance of web applications became more important to businesses as search engines (such as Google) factor in performance into their ranking. This ultimately leads to Performance == Better Visibility == More Users == More Revenue. Read more on Why Web Performance Optimization is as Important as SEO

The best way to measure the performance of your website is by looking at certain Key Performance Indicators (KPI’s) that tell you how fast or slow your web site is to the end user. Driven by efforts from web performance specialists such as Steve Souders and companies like Google and Yahoo, the industry has learned that factors such as page load time, number of network roundtrips and transferred size are important performance indicators for a web page.

With the tracing capabilities of dynaTrace AJAX Edition it is possible to extend the list of existing KPI’s to also include metrics such as Time to First Impression, Time to Fully Loaded and Time Spent in JavaScript. The dynaTrace Best Practice on Web Performance Optimization (WPO) document describes a list of KPI’s that should be tracked on every page, how these KPI’s are calculated, what dynaTrace considers as good, acceptable and not acceptable and what you can do to improve these KPI’s.


  1. Great article thanks! I’ve been using OPNET’s ACE Live, ACE Analyst and Panorama solutions for production application monitoring & troubleshooting, but I like your GUI!

  2. I have seen plenty of web applications that require J1939 to RS232 converters. I found myself in this situation earlier this week and I went browsing the internet in search for this kind of converting tool. Luckily, there are plenty of resources and tutorial our there about how, when and why to use one.
