I've inherited a web-site where certain pages 'include' over 30 files
(arrrgh!), it runs fine. In fact I'm actually very impressed with the
performance of PHP with many includes.

Never mind, I think that PHP can't handle parsing too many include files
(Files too large/complex, more than 8 include files, not enough memory/CPU
to handle PHP, whatever etc.)

I don't see your point.
Using require in a conditional block make absolutely NO SENSE, as it gets
executed wheter or not the condition of the block holds true or not.
Of course the performance "decreases" when you load more files into your
application: they need to be scanned, parsed and probably executed.

I tried both include() and require():
<?php
if(false)
{
require "some_file.php";
}
?>
and
<?php
if(false)
{
include "some_file.php";
}
?>
Both performed poorly, which is why I'm submitting this report.
At the moment, I've changed my code to use only require() without
conditions, as require() is much faster than include().
Including one more file decreases performance by 2x.
Including another file decreases performance by another 2x.
eg: If you have 8 included files, the performance would be decreased by
256x. This is the performance drop that I'm pointing out here.

You say that you use conditional statements to determine whether or not to
REQUIRE a file.
Just to make sure: You're not using require or require_once inside a
conditional block, such as:
<?php
if($condition)
{
require "some_file.php";
}
?>
I'm asking this, because require and require_once are UNCONDITIONALY called,
see the manual pages for require and include on this topic.
