OProfile <http://oprofile.sourceforge.net/> was very useful for identifying some performance bottlenecks in the softdevice plugin. No special compilation is needed, and the performance penalty is negligible (depending on the timer resolution you choose). Be sure to enable the local APIC, because otherwise OProfile won't be able to utilize the built-in performance counters of the processor. Marko
