optimilize web page loading

Hi,

i would like to know if there is a way to know how long does a web page need
to be loaded into browser ?
this is interesting fact for me, as i will optimilize my PHP code in order
to reduce this time to minimum.

i was thinking to use some timestamp but as it will be in PHP, it mean that
it should take time from server and therefore it is not fully representative
from client browser time needed to load page :-(
purpose :
mywebpage.php -> 23 s before optimalization
mywebpage.php -> 12 s after optimalization

do you have any idea ?

Try using microtime() http://www.php.net/microtime/ on either side of
your output statement(s).

Hi,

If you make use of Firefox, you can use the Yslow extension. This will
show you the bottlenecks of the page loaded (images, stylesheets,
javascripts, total duration, total size etc.).

There is a video at
http://www.oreillynet.com/fyi/blog/2...rformance.html

Browse the links from which you can see what he is suggesting without getting
the book.

Some of the things suggested are
- minimise number of files (css, js) downloaded by concatenating
- add an expires header so pages come from browser cache instead of download
- put style sheets at the top of downloaded page and (js) scripts to bottom

Someone else mentioned Yslow, which is one of the tools the author suggests.

You can use onload and XmlHttpRequest to send back the desktop client
computer date/time and compare that with your start time.

Note that you'll need to test on [a] computer[s] where you know the
date/time is set correctly, which is not true of the general visitor.

Firebug for Firefox.

You are really asking an HTML question, if you think about it.

At the PHP level, either use output buffering or assemble all your html string as a variable and
then echo it. The goal is to compress the string into the minimum number of packets.

Yes, but do so smartly. Excessive string concatenation can slow things
down as well. On most pages you probably won't notice much difference,
but I have seen instances where the difference was painfully obvious.

Depends on the server and it's load. I've strung together some rather large html strings and they
aways take far less time than the transient time on the internet. I used to use OB extensively until
one day I took the time to measure the difference. I don't recall the numbers; but, I do recall it
was not worth the slight extra trouble to use OB.

Now, I simple assemble by html strings with $report .= "foo"; And then echo $report at the end. It
also makes the code very easy to read and follow.
