NAME¶
time - Time the execution of a script
SYNOPSIS¶
time script ?
count?
DESCRIPTION¶
This command will call the Tcl interpreter
count times to evaluate
script (or once if
count isn't specified). It will then return a
string of the form
503 microseconds per iteration
which indicates the average amount of time required per iteration, in
microseconds. Time is measured in elapsed time, not CPU time.
EXAMPLE¶
Estimate how long it takes for a simple Tcl
for loop to count to a
thousand:
time {
for {set i 0} {$i<1000} {incr i} {
# empty body
}
}
