DESCRIPTION

15       This  command  will  call  the  Tcl interpreter count times to evaluate
16       script (or once if count is not specified).   It  will  then  return  a
17       string of the form
18
19              503.2 microseconds per iteration
20
21       which  indicates  the average amount of time required per iteration, in
22       microseconds.  Time is measured in elapsed time, not CPU time.

EXAMPLE

25       Estimate how long it takes for a simple Tcl for  loop  to  count  to  a
26       thousand:
27
28              time {
29                  for {set i 0} {$i<1000} {incr i} {
30                      # empty body
31                  }
32              }
