Re: PHP slowness

Hi there, just for testings sake, you should get a script that figures out the page generation time for a php script... As luck would have it, I made a class for this not too long ago. give this a whirl. First, create a php script with this in it... <?php // CREATE THE CLASS class page_gen {

       // CLASS VARIABLES
       var $start_time;
       var $end_time;
       var $gen_time;
             // USER DEFINE VARIABLES
       var $color_good;
       var $color_fair;
       var $color_poor;
             // FIGURE OUT THE TIME AT THE BEGINNING OF THE PAGE
       function start() {
           $this->start_time = microtime();
       }
             // FIGURE OUT THE TIME AT THE END OF THE PAGE
       function stop() {
           $this->end_time = microtime();
       }
             // CALCULATE THE DIFFERENCE BETWEEN THE BEGINNNG AND THE END AND COLOR CODE THE RESULT
       function gen() {
           $this->gen_time = $this->end_time - $this->start_time;
           if (!isset($this->color_good)) {
               $this->color_good = "green";
           }
           if (!isset($this->color_fair)) {
               $this->color_fair = "yellow";
           }
           if (!isset($this->color_poor)) {
               $this->color_poor = "red";
           }
           if ($this->gen_time <= 0.0999999999) {
               $this->gen_time = "<span style=\"color: $this->color_good;\">$this->gen_time</span>";
           } elseif ($this->gen_time <= 0.999999999 && $this->gen_time 
0.0999999999) {
               $this->gen_time = "<span style=\"color: $this->color_fair;\">$this->gen_time</span>";

           } elseif ($this->gen_time <= 9.99999999 && $this->gen_time > 0.999999999) {
               $this->gen_time = "<span style=\"color: $this->color_poor;\">$this->gen_time</span>";
           }
           print("<span style=\"font-weight: bold;\">$this->gen_time</span> seconds");
       }

} ?> Now, put this code at the top of the page you want to time. <?php require("cls.pagegen.php"); // or whatever you named it $gentime = new page_gen(); $gentime->start(); ?> Where you want to stop timing (usually at the bottom). <?php $gentime->stop(); ?> Now to display the time, simply go <?php $gentime->gen(); ?> It will color code it for you and everything, give it a whirl and let us know what it tells you.

Hello people, Recently, one of my webservers became rather slow. At first we thought it was the MySQL backend, but when logged in on MySQL using the command line tool over SSH, it runs as smooth as ever. Static content (normal html pages) also load without delay. It seems that the bottleneck is PHP itself. For the sake of comparison, I created 2 test pages: http://www.debuginc.com/test.html http://www.debuginc.com/test.php Everyone I asked says that the PHP page takes over 5 seconds to load while the HTML one instantly displays. The only code in the PHP page is <? echo 'hello world'; ?>. No MySQL stuff, so that eliminates the initial idea of MySQL causing the slowness. Nevertheless, it IS slow and I have no idea why or where to start looking. The phpinfo() can be found on www.debuginc.com/info.php. Any help or hints are highly appreciated. Another interesting note; this problem started a couple of days ago without any changes in the config or anything. At first I upped the amount of connections Apache would accept, but it soon turned out that was not the problem. Thanks, - Gerard
