The MyEclipse Profiler is now capable of profiling Eclipse plugins. Simply bring up the context menu on a plugin and choose Profile As > Eclipse Application

Alternatively, you could choose an existing Eclipse Application launch configuration to be profiled from the Profile toolbar item.

Profiling settings for both performance and memory profiling can be configured in the Profile Configurations wizard, accessible from the above toolbar item or your plugin's Profile As context menu.

When profiling any application from your project's context menu or the Profile toolbar item, you will now be asked if you desire Performance or Memory profiling; you no longer need to go to the Profiler Configurations wizard to select the profiling mode.
