gprof: needs compiler switches, can't profile shared libraries (?)

valgrind/callgrind instruments, slows down code by factor ~50

rsvp: OS X only, requires root

CodeXL: Windows and Linux (but no OS X), worth a try.

Ubuntu installation didn't work: Error running dpkg --configure.

traceR: An entire framework, instrumenting profiler focusing on R. Worth a try too.

verysleepy: free, worked very well last time I checked, but may require additional work to turn into a library. Windows only, but perhaps useful in combination with gperftools.
