Operating system: Mac OS X Tiger
PHP version: 5.3.0RC1
PHP Bug Type: Performance problem
Bug description: Queries like 'show keys from *' take a while to complete with
mysqlnd
Description:
------------
When using PHP 5.3 with Typo3 4.2.3, queries like 00912
$keyRes = mysql_query('SHOW keys FROM '.$tableName, $this->link);
takes a while to complete. More than 3-5 seconds.
I'm using the mysqlnd driver in Mac OS X Tiger with Apache 1.3.41
Reproduce code:
---------------
Use Typo3, and load an extension in the CMS Backend. While this does run
smoothly with PHP < 5.3, there is clearly a problem with my PHP version.
Even more: mtop show the related MySQL queries for a while (>1 second),
even if it takes less than 0.1 seconds to complete in mysql client (or
else).
Expected result:
----------------
Queries completed in less than 0.1 seconds
Actual result:
--------------
More than 3 seconds to complete, with strange behaviors such as
connection dropped or else.
