Advanced Performance Analysis

The latest Compuware APM/dynaTrace AJAX Edition 4.2

Just in time for our speaking session at SenchaCon 2013 we are happy to announce the latest version of Compuware APM/dynaTrace AJAX Edition. Version 4.2 now supports the latest versions of Firefox (FF 21 & FF 22). Download the latest version from ourAJAX Edition website.

SenchaCon 2013 Session Preview
If you happen to be at SenchaCon 2013 then consider checking out our session. I will show you how to best leverage the AJAX Edition to analyze and optimize Page Load as well User Interaction times of modern web applications for both Internet Explorer as well as Firefox. We start by giving new AJAX Edition users a brief introduction on the core functionality but will then mainly talk about advanced features and Best Practices on both browser-side performance but also the impact that modern browser technologies have on the overall application performance - especially under load.

The following screenshot shows the typical starting point when analyzing a recorded session: The Timeline View. It makes it easy to understand what impacts page load as well as user interactivity time, e.g., when opening dynamic dialogs or submitting asynchronous requests to a backend server:

Timeline View helps to understand what impacts Page Load Time.

From this view we drill further into Network Activities, JavaScript Execution, Rendering or XHR/AJAX Performance Analysis. In the session we will have a closer look at the PurePath View and the advanced features to analyze JavaScript hotspots and the impact of DOM access to end user experience. Looking forward to seeing some of you in the audience.

Getting Started with Compuware APM/dynaTrace AJAX Edition
I want to highlight several resources that will help new and experienced users:

Stay tuned for regular updates of the AJAX Edition. We always try to keep up with the frequent new versions of Internet Explorer and Firefox.

The challenges of aggregating data from consumer-oriented devices, such as wearable technologies and smart thermostats, are fairly well-understood. However, there are a new set of challenges for IoT devices that generate megabytes or gigabytes of data per second. Certainly, the infrastructure will have to change, as those volumes of data will likely overwhelm the available bandwidth for aggregating the data into a central repository. Ochandarena discusses a whole new way to think about your next...

Cell networks have the advantage of long-range communications, reaching an estimated 90% of the world. But cell networks such as 2G, 3G and LTE consume lots of power and were designed for connecting people. They are not optimized for low- or battery-powered devices or for IoT applications with infrequently transmitted data. Cell IoT modules that support narrow-band IoT and 4G cell networks will enable cell connectivity, device management, and app enablement for low-power wide-area network IoT. B...
The hierarchical architecture that distributes "compute" within the network specially at the edge can enable new services by harnessing emerging technologies.

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...
