1 Following are examples of running tcl_cputime.d. 2 3 Here it runs while we execute Code/Tcl/func_slow.tcl 4 5 # tcl_cputime.d 6 Tracing...

The first section represents 49 the ten most commonly executed commands while the script is tracing. 50 51 The exclusive function on-CPU times show that func_a spent around 0.5 seconds 52 on-CPU, func_b spent about 1.0 seconds, and func_c, 1.6 seconds. This excludes 53 time spent in other procedures or commands. 54 55 The inclusive function on-CPU times show the time spent by these procedures in 56 total, including the time spent in other functions called, and since func_a 57 called func_b which called func_c, these times make sense. 58 59 These on-CPU times are the time the thread spent running on a CPU, from when 60 the function began to when it completed. This does not include time 61 spent off-CPU time such as sleeping for I/O or waiting for scheduling. 62 63 On-CPU times are useful for showing who is causing the CPUs to be busy. 64 See Notes/ALLoncpu_notes.txt for more details. Also see 65 Notes/ALLexclusive_notes.txt and Notes/ALLinclusive_notes.txt for a 66 detailed explanation of exclusive vs inclusive function time. 67 68
