This times excludes time spent in 249 other functions. 250 251 The inclusive function on-CPU times show that func_a spent around 1.4 252 seconds on-CPU. This includes the time spent in other functions called. 253 254 These on-CPU times are the time the thread spent running on a CPU, from when 255 the subroutine began to when it completed. This does not include time 256 spent off-CPU time such as sleeping for I/O or waiting for scheduling. 257 258 On-CPU times are useful for showing who is causing the CPUs to be busy. 259 See Notes/ALLoncpu_notes.txt for more details. Also see 260 Notes/ALLexclusive_notes.txt and Notes/ALLinclusive_notes.txt for a 261 detailed explanation of exclusive vs inclusive subroutine time. 262 263
