[TYPO3-english] huge amount of queries to tx_extbase_cache_object table

i've tried to disable extbase object and reflection cache by adding the following lines to my ext_localconf.php file. This worked for reflection cache but my settings for object cache are ignored, therefore i still have 233 queries in my log.
I've tried APC backend, this increases performances a bit but does not reduce the number of queries.
And yes, Caching framework is activated.

Seems like the backend for extbase cache object is always ignored.

//$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['cache_extbase_object']['backend'] = 't3lib_cache_backend_ApcBackend';
//$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['cache_extbase_reflection']['backend'] = 't3lib_cache_backend_ApcBackend';
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['cache_extbase_object']['backend'] = 't3lib_cache_backend_NullBackend';
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['cache_extbase_reflection']['backend'] = 't3lib_cache_backend_NullBackend';
