We recommended Oprofile from a longer history of using it, and that's
it. I've actually switched over to using valgrind for all of my
analysis and profiling work. In many ways, I still prefer Oprofile
because it works within the Linux kernel, but recent updates to Ubuntu
have made it much more difficult to install and use Oprofile, and I
can't be bothered any more to worry about stuff like that. So valgrind
with callgrind works great and it's now my tool of choice.

But we should probably update the wiki to include information about
using callgrind wit Kcachegrind.
