[PHP-BUG] Bug #51610 [NEW]: 1 second+ needed for OCI8 versus PDO/oci to open/close connection and exit

From:             
Operating system: Linux & Snow Leopard
PHP version:      5.3SVN-2010-04-20 (snap)
Package:          OCI8 related
Bug Type:         Bug
Bug description:1 second+ needed for OCI8 versus PDO/oci to open/close connection and exit

Description:
------------
Is this normal to see the native OCI8 1.3.5 or later requiring additional
time to 
run code snippet shown below when accessing Oracle 10.2.0.4. I'm seeing
this at 
work as well (SUSE Linux).  Therefore, I have stayed with OCI8 1.2.5 for
the 
moment.

Notice how the time is the same when using the PDO/OCI interface.


Test script:
---------------
# Native OCI8 Performance:
#
# PHP 5.2.14 201004191430, OCI8 1.2.5:  ~ 0.15 seconds ;this is nice
#
# PHP 5.3.3  201004191430, OCI8 1.2.5:  ~ 0.25 seconds ;takes 0.1 extra
here
# PHP 5.3.3  201004191430, OCI8 1.3.5:  ~ 1.20 seconds ;slowness begins
when
# PHP 5.3.3  201004191430, OCI8 1.4.1:  ~ 1.20 seconds ;script exits for
1.3.5+
# PHP 5.3.3  201004191430, OCI8 1.4.2:  ~ 1.20 seconds

<?php

$conn = oci_connect('hr', 'hr', '//localhost:1521/mac10g');

if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

oci_close($conn);

exit;

?>

# PDO/OCI Performance:
#
# PHP 5.2.14 201004191430, OCI8 1.2.5:  ~ 0.15 seconds ;very fast
#
# PHP 5.3.3  201004191430, OCI8 1.2.5:  ~ 0.15 seconds ;same as PHP 5.2.14
:)
# PHP 5.3.3  201004191430, OCI8 1.3.5:  ~ 0.15 seconds ;very happy to see
this
# PHP 5.3.3  201004191430, OCI8 1.4.1:  ~ 0.15 seconds ;with 1.3.5+
# PHP 5.3.3  201004191430, OCI8 1.4.2:  ~ 0.15 seconds

<?php

try {
    $conn = new PDO('oci:dbname=127.0.0.1/mac10g', 'hr', 'hr');
}
catch (PDOException $e) {
    trigger_error("Could not connect to database: ". $e->getMessage(),
E_USER_ERROR);
}

$conn = NULL;

exit;

?>


Expected result:
----------------
I'm hoping that PHP 5.3.2+ with OCI8 1.4.1+ can perform as fast as PHP
5.2.13 with 
OCI8 1.2.5 when using the native driver.  This is why I have stayed with
1.2.5 at 
work.

It wasn't until tonight that I saw the times the same via the PDO
interface. That 
made my day.

Actual result:
--------------
The native OCI8 1.3.5+ requires extra time to open/close and exit.  The
time delta 
is 1 second for such a small code snippet.
