Getting Familiar with the Optimizations Tab

The JRA records all optimization events that occur during the course of the recording. JRockit uses JIT compilation for the initial conversion to machine code. The most commonly used methods are then further optimized during the application run. This information is then displayed in the Optimizations tab (see Figure 10-1).

Figure 10-1 Optimizations tab

Optimizations tab

The Optimizations tab is divided into the following sections:

  1. Optimization-this section displays the before and after scenario of the optimizations that have taken place.
  2. Methods Optimized During Recording-this section displays which methods that have been optimized during the recording, i.e. this is necessarily not a full list of all optimizations that are performed for your application.
