speed/resource test tools?

[unknowncat]

anybody know a tool i can use to test a scripts cpu/ram useage?  I have a script that's overwhelming the server, need to find out which part of the script is causing the problems.  also, anybody know ways to tell a script to use less resources?  thank you

you could use sus_getloadavg() to get the load average in the past 1, 5 and 15mins and use this to help determine which processes are overwhelming the server.

thanks joel.  I know which script it is., just need to find out which lines are to blame and how to manage them into pieces or somehow set delays or ram clearing to minimize the impact on the server.

check your log files

Then use a script to determine which parts of the script are taking the longest, i.e. to find faulty loops etc

$start = microtime();
$duration = array();

$x = 0;
//loop here
while ($x < 15000) {
$x++;
}

$duration[] = microtime() - $start;

$start = microtime();

$x = 0;
//loop here
while ($x < 15000) {
$x++;
}

$duration[] = microtime() - $start;

foreach ($duration AS $key => $value) {
echo "Section $key Duration: $value<br/>";
}

 

 

and then use set_time_limit(), also checking what hte limit was set to
