Very old versions of Maemo Mapper did exactly that. Very old versions of Maemo Mapper felt faster to me than newer versions did. Hmmm.

Profiling applications (oprofile, others?)
Hi all, since fremantle's maemo-mapper is so horribly slow, I went and tried to run oprofile. Unfortunately it seems to me that static functions never appear in the final report. Is this how it is supposed to work? What other profiling tools can you recommend?
