TheMSsForum.com >> IIS >> Urgent -Problem with IIS 6 Performance

Hi

The server is a co-located Xeon 3.0ghz. I am running win2003 with IIS6 and
PHP 4.38. When I run a page with an embedded PHP script that generates
simple output, it runs quickly when accessed via IE6 locally on the server,
or at the co-location facility. When accessed from an outside site, it runs
extremely slowly, and then times out. The final html page is about 4kB.

<?
function getmicrotime(){
list($usec, $sec) = explode(" ",microtime());
return (substr($sec,7,3) . substr($usec,1,4) );
}
?>
<head>
</head>
<body>
<?
for ($i=1;$i<=10;$i++) {
for ($j=1;$j<=250;$j++) {
print "$j";
}
$time_start=getmicrotime();
print " $i $time_start &  ";
}
?>
</body>

when the output page page is preformatted (php is not dynamically generating
it) it does respond very quickly. i think it is something in the byte by
byte generation and transmission of the page.

My guess is something in the TCP/IP configuration is wrong, but I don't have
a clue what.

This problem is very urgent. I'd appreciate any insights.

Hello Howard,
from you problem description it sounds like you are experiencing a network
level issue not and application level issue.

This is a known buffering issue in HTTP.SYS that will be fixed in WS03SP1.

See:
http://support.microsoft.com/default.aspx?scid=kb;en-us;840875 for
temporary relief until the real fix is released (the real fix is not as
simple as just changing a registry key -- the registry key only addresses
some issues but not all).
