Interesting approach... yet: My results for above 31.017u 0.007s 0:31.14 99.5% 1544+918k 0+0io 0pf+0w You can optimize it some more: <?php $a = 10000000; $i = $a; while( $i-- ){} ?> these results 19.008u 0.031s 0:19.58 97.1% 1544+918k 0+0io 0pf+0w Curt -- "I used to think I was indecisive, but now I'm not so sure." -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
