Shell Programming and Scripting

hiho,

any ideas?
why is this little script about 1000% slower on solaris than on linux:

<?php

function GetMicrotime(){

list($microseconds, $seconds) = explode(" ",microtime())
;


return ((float)$microseconds + (float)$seconds);

}

$start = GetMicrotime();

$ende = GetMicrotime();

$time[] = $ende-$start;

for($x=0;$x<200;$x++)

{

for($i=0;$i<2000;$i++)

{

$great_dump[] = array(1233,1233,455);

}

$ende = GetMicrotime();

$time[] = $ende - $start;

}

$time=array_reverse($time);

foreach($time as $zeit)

{

print "\n";

printf("%.10f",$zeit);

}

?>

testet with:
# time php script.php
php 4.3.4

some results:
