Bug Type: Performance problem
Operating System: Linux 2.6.5-7.282-bigsmp
PHP Version: 5.2.0
New Comment:
If I put date_default_timezone_set("Europe/London") at the top,
performance is fine.
But what was causing the slow-down and memory-usage? Any why only with
the with the array assignment (Which was not timed)?
Is it something to do with the E_NOTICEs? A notice was generated in
E_STRICT on 5.1.6 but it didn't affect performance.

I don't understand what you're talking about.
Your code works 3x faster with 5.2.0 even WITH the array stuff.
0.37447214126587 (5.2.0) vs 0.96990513801575 (5.1.6)
Try to set the timezone correctly?

If I remove the strtotime() and just have the 4000 element array, it
also works faster.
If I just remove the _assignment_ from the return_some_stuff() if also
works much faster.
But this is a sumation of a live peice of code. I want to make a 4000
array and then call strtotime 3000 times times (Is this so Odd?). This
is 10 times slower in 5.2.0 and uses 30 times as much memory.
If I take out all the code and just have "echo 'Hello World'", It's
also much faster, but that's not quite what I want to do!

If you remove the 4000-elements array, 5.2.0 works 3x-4x times faster
than 5.1.6.

derick, but how does that compare to 5.1.6?
The memory increase during the strtotime() loop, I see is with no
php.ini (php -c /dev/null).
E_STRICT gives me warnings on both 5.2 and 5.1.6, "strtotime(): It is
not safe to rely on the system's timezone settings... " etc.
Is it perhaps something to do with logging this warning? I thought if
strict was turned off it didn't log the error at all.

Works fine for me, do you have error_Reporting set to E_ALL | E_STRICT
?
