Thirteen performance gurus answered ... More >

Check out EnterpriseJS.io which is "A COMMUNITY FOCUSED ON ELEVATING JAVASCRIPT DEVELOPMENT FOR THE ENTERPRISE THROUGH COLLABORATION, CONVERSATION, AND EDUCATION".

Manage the Cost of a Feature through Performance and Resource Budgets

Having a performance budget for a feature is a widely discussed approach that I’ve been proposing for a performance oriented culture for a long time. In addition to Page Load Time – primarily used to derive the User Experience – I recommend  including key quality, performance and scalability metrics to define, implement and approve new features. As revealed in the blog “We only control 1/3rd of our page load time” we have only a fraction of the actual response-time budget ... More >

Shift-Left Quality with Dynatrace Personal License

In the past year I have helped scores of developers, testers, architects and ops analyze the quality, performance and scalability problems of the business critical apps for which they are responsible. They shared their data via Share Your PurePath which allowed me to provide them quick feedback on the technical root cause of why an application won’t scale or is slow. All of these fine people had one thing in common: They looked into the issue when it was almost or already ... More >

Content Debt: Underestimated User Experience & SEO Impact

In recent weeks I ran across several instances of "Content Debt". What is content debt? Like technical debt, content debt slows our content management systems down and impacts our end users in the event we do not follow common best practices and not constantly monitoring for outdated content on our web sites. The most recent example of content debt I encountered was actually from the STPCon Web Site (I love STPCon – but unfortunately they ran into a very classic issue). ... More >
