# Launching a Profile

Perf plug-in provides useful profile information in a user-friendly interface, gathering the required information from the Perf command-line tool and hooking it into the Eclipse and CDT's facilities.

During a profile run, the Perf plug-in will start, stop and perform other Perf tasks in the background as needed, while the binary being profiled runs as normal.

## One-click launch

The Perf plug-in for Eclipse includes a one-click launch feature which profiles the binary with default options. To use the one-click launch, right click on the project, the binary or in an open editor for a source file belonging to that project. Then, navigate to Profile As and click Profile With Perf to start the launch.

## Launching a Customized Profile

The Perf plug-in allows you to configure a profile run using several options. These options are exposed via the launch configuration in a user-friendly manner, allowing for a more complex profile.

To customize a profile, right click on the project, the binary or in an open editor for a source file belonging to that project. Then, navigate to Profile As > Profile Configurations... to open the Profile Configurations menu. Refer to the Profiling Configuration section for more information about configuring a profile.

After configuring a profile, click the Profile button to launch the profile.
