The PROFILER at least gives information about the time spent in
routines:
IDL> profiler, /system
IDL> for i = 0, 9 do $
IDL> foo = smooth( rebin( randomu( seed, 100, 100 ), 200, 200 ), 5 )
IDL> profiler, /report
Module Type Count Only(s) Avg.(s) Time(s) Avg.(s)
RANDOMU (S) 10 0.055057 0.005506 0.055057 0.005506
REBIN (S) 10 0.032079 0.003208 0.032079 0.003208
SMOOTH (S) 10 0.036360 0.003636 0.036360 0.003636
