Start with `apropos performance monitoring features built into the kernel'.
This gives among other things:

perfmon(4)               - CPU performance-monitoring interface
gprof(1)                 - display call graph profile data
kernbb(8)                - generate a dump of the kernels basic-block profile buffers
kgmon(8)                 - generate a dump of the operating system's profile buffers

kgmon is the most relevant.  It only matched the keyword `the' in the
above apropos command :-).
