It's mostly trial and error here, and for that you'll want to use any of the
web server benchmarking tools to help out ( such as 'ab' if you are using
apache ).
You might want to google up some of Rasmus's presentations on optimization
to get a better idea on what to do. Here's a good one to get started on
http://talks.php.net/show/tortech04/26.

i wish i could tell you a benchmark tool, but I dont really know one.
if u find something, please let me know.
one think what you could / should do is to encode the php scripts.
If u encrypt it or not, its up to you, but note, if u encode php scripts you
can save up to 60% of the speed (and even memory), because the most time
which is passing by, while your script starts, is the time which php needs
to parse, check and interpret the script in bytecode. After the script is in
bytecode php run the script. By encoding your script these steps falls away,
cz the encoder save the php scripts directly in bytecode :)

Betreff: Re: [PHP-WIN] Optimization/Benchmarking tools?
John,
Thanks for the tip. In just a short time, this tool helped me to find
the big bottlenecks in my scripts.
However, as far as I can tell, the Xdebug profiler gives no information
on the loading/parsing phase of PHP script execution. I would like to
determine how much benefit I can get by taking steps to reduce PHP file
sizes, for example (removing comments, breaking up large classes into
several files, etc.) or by refactoring the code so that I can use
exclusively require() instead of require_once().
Can anyone suggest a tool for measuring this?
Thank you,

I've reported the problem as php-bug.

I found a solution and figured I would share with the everyone.
I was able to switch my request method over to POST (instead of GET). I
am now doing testing to make sure that this will meet my needs, but so
far it seems to work well.
This function accepts the data to post and then returns the resulting
page. the response page does not have to be html, but I have only tested
with text. I don't know how data would work. Data to be posted should be
in name=value&name1=value1 format.
//###################################################################
// post_and_retrieve function
//###################################################################
function post_and_retrieve($host, $path, $data_to_send) {
$errno = 0;
$errstr = '';
$conn_timeout = 30;
$headers = '';
$content = '';
$flag = false;
$lc = 0;
$content_len = 0;
$fp = fsockopen($host,80, $errno, $errstr, $conn_timeout);
if (!$fp || $errno != 0 || $errstr != ''){
return "FAIL errno: $errno, errstr: $errstr";
}
fputs($fp, "POST $path HTTP/1.1\n" );
fputs($fp, "Host: $host\n" );
fputs($fp, "Content-type: application/x-www-form-urlencoded
\n" );
fputs($fp, "Content-length: ".strlen($data_to_send)."\n" );
fputs($fp, "Connection: close\n\n" );
fputs($fp, $data_to_send);
// remote script will now process the post and return a result
while (!feof($fp)) {
$res = fgets($fp,8192); //read 8k/line from remote host
if ($flag) {
if ($lc == 0) {
// first line contains the content
length in hex
$content_len = hexdec(trim ($res));
} else {
$content .= $res;
}
$lc++;
} else {
$headers .= $res;
if (strlen(trim($res)) == 0) {
$flag = true;
}
}
}
// trim our content to content_len
$content = substr ($content, 0, $content_len);
if ($headers === FALSE || strlen ($headers) < 1) {
return "FAIL could not read response content: $content";
}
fclose($fp);
//$return = array('headers' => $headers, 'content' => $content);
$return = $content;
return $return;
}
Thanks,
James
