• Simplify the overall development experience

In Spring ’11, you’ll find a new summary tab in the executed units section of the System Log Console that highlights the duration and composition of a request. Providing this data makes it easy for developers to identify and isolate execution hot spots, thus simplifying the development experience. There is also a new "variables" section that details the variables during a request, so developers can verify that assignments are being made correctly.
