Firstly, I narrowed it down to the following code:
$Output = SimpleItem("$Heading","",true);
foreach ($TopList as $Player => $Qty) {
$Output .= SimpleItem(WebLink("
$Player","csstats.php?id=" . $PlayerStats[DETAILS][ID][$Player],"bar'
style='CURSOR:crosshair;"),$Qty);
}
print $Output;
This loop scored a maximum process time of almost 28 seconds!
However, most of the "bad" calls were from 2 to 10 seconds, with the good
ones once again clocking at around 0.001 or less.
<b>Note that during the tests, the array within the foreach loop always
contains 10 elements.</b>
Two other functions are called here: SimpleItem, and WebLink. Both of these
test out ok, with maximum test times of 0.019 and 0.0077 respectively, so
that should rule them out. I've included the code for those two functions
at the end. 10 iterations gives a maximum TOTAL process time for SimpleItem
at 0.19 seconds, and 0.077 for Weblink. That's still way short of the 28
seconds for the entire chunk.
Next step was to take out the print statement, and you know what? The run
time for the loop dropped to a maximum of 0.1 sec.
That narrowed it down to "print $Output;"
I then proceded to check the length of $Output and it's run time, and got
the learned that the string is 2112 characters long, and sometimes takes a
fraction of a second to print, while other times takes several seconds.
Even if I print the SimpleItems separately rather than appending to a
variable (the way it was set up originally) the problem remains.
So, why should this print statement take so long?
