Rob here recently made an initial release of OProfileUI, a GTK+ frontend to the excellent OProfile stochastic system profiler.

We’re big fans of OProfile especially when it comes to optimising code on ARM but it can be a little painful to set up and use at times. OProfile-UI hopes to improve that a little with both its configurable graphical view of collected statistics and support for connecting and collecting data from a remote target machine. See the OProfileUI Projects page for further information and source code.
