I've a question regarding a bit of code I have. On my site I have a
set of semi-static data (changes once a month or so) that needs to be
displayed in various places around the site and integrated with
dynamic data being fed in from a MySQL database.
At the time of development I chose to put this semi-static data in to
an array and include() it where required. However, the array is now
getting quite big. It has 1200 entries of the form:
$myArray["item1"]["Property 1"] = "Value 1";
$myArray["item1"]["Property 2"] = "Value 2";
$myArray["item1"]["Property 3"] = "Value 3";
$myArray["item1"]["Property 4"] = "Value 4";
$myArray["item1"]["Property 5"] = "Value 5";
$myArray["item1"]["ArrayProperty"][] = "Other Value 1";
$myArray["item1"]["ArrayProperty"][] = "Other Value 2";
$myArray["item1"]["ArrayProperty"][] = "Other Value 3";
$myArray["item1"]["ArrayProperty"][] = "Other Value 4";
The PHP file it is in weighs in at 550KB and is used in most of the
custom data driven pages I have.
My question is how much of an effect will this design choice have on
the performance of my Linux/Apache/PHP/MySQL server that is running on
a Celeron 1.7Mhz/512MB machine?
My site is fairly busy with over 300 concurrent users at peak times
and I am currently experiencing high loads during these peak times. I
disabled the sections of the site that use this file during a peak
time and found the load to be a lot better. However, there are other
things within these sections that could be causing high loads - I
would just like to rule this out as a possibility.
Thanks for any advice you can give,
Steve
