dynaTrace provides one of the most powerful tools for analyzing the performance of web applications in Internet Explorer. In this talk, dynaTrace engineer Alois Reitbauer walks through four specific analytic scenarios using the dynaTrace interface.

In this screencast we discover what typically causes Ruby server memory bloat, namely instantiating too many ActiveRecord objects. Thankfully there are several plugins which can help you detect when your application needs some help, and where your application is hurting the most. We start by taking a look at Rack-Bug, a toolbar which places all sorts of statistics about each requests at your fi...

Every good developer loves building a bonsai-site—a fast, lean paean to minimalism and efficiency. The DOM tree is carefully pruned, lovingly decorated with tasteful CSS. The browser welcomes it with a sigh of relief. The server’s CPU barely registers, and the database brushes delicately against the SAN, no lookup un-clustered. Inevitably, such perfection is short-lived. Once the si...

Learn how to set up instrumentation for both code coverage and profiling in a deployed ASP.NET application, rather than an application running from within Visual Studio. This video follows the steps set out in the Profiling ASP.NET in Instrumentation mode from the Command Line TechNote on the Microsoft MSDN Web site. Presented by Chris Menegay Date: 22 August 2007

In this video we learn that Visual Studio Team System provides two methods of profiling a Web application: Sampling and Instrumentation. Instrumentation injects markers in the underlying code so that the developer can view full details of the application's execution, including call trees and object allocation, to help tune the performance of the application.

This demo shows three of the new profiler features in the NetBeans IDE: a drill down graph that makes it easier to see which categories your application is spending time in, profiling points that allow you to control the profiler's actions from within your application, and a heap walker for tracking down memory leaks.
