Page was generated in 0.314618 seconds

rsphaeroides · **Posted:** Wed Nov 16, 2005 5:20 pm

Is there a way to add the page generation time to the frontend. At the bottom of every page when I'm logged into the backend I see a message like "Page was generated in 0.314618 seconds"

I'd like to have this done on pages in the frontend while I'm developing so I can see the effect of different components, modules, and bots and how changes in queries on my custom stuff changes the page generation time.

Thanks

Didn't think this through, but if you put
$starttime = time();
in the beginning of your index.php and
$endtime = time();
near the end, and then show the difference, wouldn't you more or less be where you want?

Interesting.

I tried it ludo... nothing happened. :'(

Code:

<body>
<?php $starttime = time(); ?>

blah blah blah

Code:

<?php $endtime = time(); 
$pagetime = $endtime - $starttime;
echo $pagetime;?> <br>
<?php echo $endtime; ?> <br>
<?php echo $starttime; ?>
  </body>

tried this, and I get

1
1132163478
1132163477

at the bottom of the page

is time that seconds since 1972 value? wanted something with a little more precision...

Also I wasn't quite sure where to put it relative to head and body?

OK
change to microtime() and you get time in microseconds now I have

0.182749
0.25116700 1132163988
0.06841800 1132163988

just a minute and I'll clean it up a little and add the this page was generated...

Hmm..
Maybe not
some of my pages are giving negative times???
Would be fantastic if it were true, but I suspect not??

Any other suggestions or point out where I've mucked it up??

stingrey over at http://www.stingrey.biz/ has at the bottom of the page something that says:

Quote:

Page loaded in 0.061 seconds.

Is this what you are asking? Might want to PM him about how he did it.

Near beginning of template's index.php file:

// Start page load timer ...tick tock...
// -----------
$tstart = mosProfiler::getmicrotime();
?>

Near end of template's index.php file:

// Display page generation time...
// ---------
$tend = mosProfiler::getmicrotime();
$totaltime = ($tend - $tstart);
printf ("Page was generated in %f seconds", $totaltime);
?>

Yes this is what I want. I'm sure Rey is using a cleaner way to do it, but I figured out what was wrong with the above.
microtime returns both the number of seconds since the UNIX epoch (1970 not '72...) and the number of microseconds separated by a space so you have to explode the string and put it back together as a float then do the subtraction. The negative values came in when the seconds turned over...

This works.

After the body tag

Code:

<body>
<?php
function microtime_float()
{
   list($usec, $sec) = explode(" ", microtime());
   return ((float)$usec + (float)$sec);
}

$time_start = microtime_float();
?> 
<?php $starttime = 0; $starttime = microtime (); ?>

before the tag

Code:

<?php $time_end = microtime_float();
$time = $time_end - $time_start;
echo "This page was generated in $time seconds\n";?>
<br> start
<?php echo $time_start; ?>
<br> end 
<?php echo $time_end; ?>
  </body>

Thanks for the start.

What exactly do "Near beginning" and "Near end" mean? can I have one in the head, before the , after the anywhere I want...?

And while we're at it, any comment on what a reasonable value is, and when you'd want to start worrying? Most of mine are coming in under 100 ms but about 10% are 100-300 ms.

How fast is fast and how slow is slow?

I usually put it after the statement and right before the statement...

Really defends on server environment, shared versus dedicated, CPU speed, memory size, number of concurrent users, tuning and optimization of OS, php, mysql, etc. Personally, I consider anything under 1.0 second to be reasonable.
