Yes, the two servers I tested on have sessionn.use_trans_sid enabled, I
am unsure of the third since it is not my server.
Neon, two of the three servers tested on have next to no traffic,
server load is not a possibility. ESPECIALLY since the slowdown is
consistant, happens every time at the same point.

Does the server's have "session.use_trans_sid" enabled?
(check with e.g. 'echo ini_get("session.use_trans_sid");' or from
phpinfo() output)

Not a bug, check if you server is under heavy load etc..

I can't, I don't run the server, but I've tried it on three seperate
servers so far and all have the same result. Two are companies offering
hosting, and another is a private server.. they should have correct
configurations in their php.ini which leads me to believe that there is
some unexpected slowdown when the buffer is increased.

Nothing wrong here, must be something wrong in your configuration, try
copying the php.ini-dist file from the distribution over your php.ini.

Description:
------------
When using large ammounts of html (printing all at the same time or
not) there is a major slowdown while php increases the buffer to allow
for more html to be outputted. This is not a bug specific to my
software as you can see in example, it should NOT take 1 second to
execute phpinfo() when my entire script can (when not using large
ammounts of html) execute in 0.05 seconds... if it hits those large
ammounts though, the buffer goes up as well as the time, sometimes all
the way up to 1 or 2 seconds which is rediculous. IF output_buffering
is set high enough in php.ini it runs perfectly fine in the time it
should, but since this is not changeable via script it becomes a major
problem for scripts that need to output large ammounts of data jumping
to multiple seconds of execution time when it should only be a portion
of a second.
Reproduce code:
---------------
<?php
function getmicrotime()
{
$time = explode(' ',microtime());
return ((float)$time[0] + (float)$time[1]);
}
$timeStart = getmicrotime();
phpinfo();
print (getmicrotime() - $timeStart);
?>
Expected result:
----------------
It to execute in much under 1 second.
Actual result:
--------------
It executes in anywhere from 0.8 seconds to over 1 second.
