I have a strange problem with PHP 4.0.4pl1 and above. It looks like including 
a file that contains classes can become a major performance bottleneck

My machine is an Intel Pentium ]I[ 667Mhz, 128Mb RAM running RedHat Linux 
7.1; I installed PHP as a DSO module. I used ab (Apache Benchmark) for 
benchmarking. The following application runs a very simple query and outputs 
the result:

  $db = pg_pconnect("dbname=jokes user=foo password=xxxxxxxxx");
    $res = pg_exec($db, "SELECT * FROM j_jokes ORDER BY posted DESC LIMIT 
    echo "<table>";
    for ($i=0; $i<pg_numrows($res);$i++)
      echo "<tr>";
      $row = pg_fetch_row($res, $i);
      for ($c=0;$c<count($row);$c++) echo "<td>$row[$c]</td>";
      echo "</tr>";
    echo "</table>";

It can process up to 200 requests per second depending on the size of the 
dataset. Sometimes it can do even more than that. I didn't optimize Apache 
and PostgreSQL for performance.

However, the following "application"

can process about 25 requests per second. 

  My applications use Smarty, Pear DB and my own classes from several include 
files. Thus, they can hardly handle 10 requests per second. I tried to 
benchmark them in many different ways and I figured out that *including* a 
class takes a lot of time. Using those classes doesn't seem to change 
anything dramatically.
  Is it an inherent problem of using classes with PHP or is there something I 
can do about it?
