RE: [PHP-WIN] Re: Speed issues

So if I understand this correctly. If a client has a very slow connection and the page content is large. The difference in time between the top of the script and the bottom of the script should be large. So I have effectively been monitoring client time to download page content. If this is so, thanks for shedding some light on a 3 year old issue.

Killmer Cc: Windows Helplist (PHP) Subject: Re: [PHP-WIN] Re: Speed issues The problem you are experiancing is that your script is sending infomation to the user, waiting for the reply, and doing this for EVERY output. Basically, the time you are recording is actually the time taken for the user to load the HTML code for that page. If you only want the time taken to generate the page, you must use output buffering so that no infomation is sent to the user BEFORE the entire page is completed. Output buffering is a very useful features, and can help improve performance. It also allows for gzip compression on the output, so less bandwidth per page is used. I suggest looking in the php manual for output buffering Stephen ----- Original Message ----- From: "Charles P.

I use the same getmicrotime functions to get down to the milliseconds that the page excution takes. What I am seeing is in these log files. Some times a single script will take 30+ seconds but other times that same script takes <1 second. I have even seen this in a script that has only a single if-then statement. No other code exists in that script. My only thought is that if a client gets a very slow connection maybe that would cause a queue to form somewhere.

So I built this funtion to see how long it really takes to create. I believe it is IIS serving up the webpage that makes it takes so long. Put the start time at the beginning of the script and the end time at the bottom (footer??)..Here ya go: function getmicrotime() { $bits = explode(" ", microtime()); return $bits[0] + $bits[1]; } //this gets the start time it takes to run a script $time_start = getmicrotime(); // lets get the ending time $time_end = getmicrotime(); $total=$time_end-$time_start; $total_format= number_format($total,4); print "Created page in $total_format sec(s)"; "Charles P.

PHP 4.3.1 CGI mode IIS 5.0 Windows 2000 Server Every now and then I get scripts that take > 30 seconds to complete. The same script usually takes < 1 second. Could a client on a VERY slow connection be slowing this process down? In a request process who handles queueing the data until the client can download all of it? IIS or PHP or both?
