Yes, I think it takes quite some time to source pm-functions. In that list you can see that 95led, which does not source pm-functions, takes one order of magnitude less to run. What do you mean with "everything should still be in cache"? If you mean that pm-functions are supposed to be source at the beginning only, then it's not happening with my pm-utils "light", since it is implemented in C. But I don't think that is the case, since pm-utils in run_hooks doesn't source the hooks, but executes them as well. If you mean the CPU cache instead, then nope: the CPU of the FreeRunner throws away the whole cache at every process switch.
