Bug description: output buffer timing is strange
on Windows 2000 SP2 FR, and php 4.2.3, the outbut buffer seems to not work
correctly.
i make test to see the time taken to output data, and this time is not
linear.
explain, with output buffer = on in php.ini, all works fine. but with
output_buffer=off ou output_buffer = 4096 or 8192 or more, the time for
output data is very strange.
the script:
<?
include "exectimer.class.php";
$tip = new VWT_execTimeProfiler();
$suite = " vs print";
$max = 10000;
$tip->start();
$tip->watch("echo double");
for( $i=0;$i<$max;$i++) {
print "echo $suite";
}
echo "<hr>";
$tip->watch("echo en simple");
for( $j=0;$j<$max;$j++) {
print 'echo '.$suite;
}
$tip->stop();
$tip->show();
?>
the first for loop can take 100 ms to 800 ms when i change the size of
output buffer.
if i increase the loop count, then the time for the second loop inrease,
but the firt loop decrease.
When output_buffer is on, all works fine.
I don't see this bug on Linux.
PS: sorry for my bad english...
