In the future, it would be nice to have the ability to compare results of profiling the same binary. For example, in the simple case, suppose a user made a change to some method and wanted to test how the new change affected performance. They could run one session before the change, and one after. They could then specify that they want the 2 sessions to be compared and displayed in an easy to understand format. The work for this functionality in Eclipse OProfile existed in a branch in our old svn repos, and it shouldn't be too difficult to adapt this to work for perf.
