resource usage

[KapTinKiRk]

Some scripts use a lot of system resources, some don't. Is there a way to test a script and see how much resources it uses? It it simply the bandwith, or is it a whole other thing in itself.

Usually system resources refers to the memory and CPU a process takes up. Run the script, and if you have shell access run 'top' and see how much your script or program uses.

The shell script 'top' is probably more accurate, but you can also use the perl Benchmark module. It is mainly used for testing a block of code. You use it like this:



use Benchmark;

$t0 = new Benchmark;
# code you want to test
$t1 = new Benchmark;

print "<p>Processing Time: " . timestr(timediff($t1, $t0)) . "\n";
