Do that alot for an average. Justin

Ron -- Unsubscribe? mail -s unsubscribe [EMAIL PROTECTED] /dev/null Since Perl is an interpreted language, there are no assurances as to how long it will take to run your script, because it highly dependent on how Perl decides to process your instructions. CGI scripts typically are under their own process anyhow, so it also depends on when the OS decides to schedule your script for execution. Since Linux is not a Real Time OS there are no assurances on either front. The point being that you can get a pretty good average (down to a tenth of a second) in testing, but execution time may widly vary under a heavy system load. Solution: Average time under a heavy load and feel comfortable with an average. Justin
Re: Time taken by a script
Ron is rights, but you can get an idea when you do prepend the time command like: time script It gives you a few stats.

Time taken by a script
I've written a cgi script in perl an I would like to know how long (exactly, 10th of second) it takes to execute the script, how can I do this? Ron
Re: Time taken by a script
Ahoy
You ask:
I've written a cgi script in perl an I would like to know how long
(exactly, 10th of second) it takes to execute the script, how can I do
this?
Here's a crude way:
#!/usr/bin/perl
$now = time();
for( i=0; i10; i++) {
require(thescriptIwanttotime.pl);
}
$then = time();
$elapsed = (($then - $now) / 10);
print $elapsed;
exit;
