Cache not delivering? - magento

Question

I recently updated to magento 1.9 but found my categories very slow. I couldn't find the problem so guessed this had to do with magento 1.9 and decided to downgrade to magento 1.8. Everything was working fine then, but after a while magento became slower again. I had made some changes due to some other errors, as I slightly changed /etc/local.xml. Obviously, I undid it again, even though it should not have been the reason in the first place. Unfortunately, this didn't solve my problem.
My current local.xml:
<cache>
<backend>Cm_Cache_Backend_File</backend>
<prefix>SH24_</prefix>
</cache>
Cm Cache Backend is definitely working. Same results when using standard cache.
I turned on the profiler, and how files are delivered looks completely different on a different development page.

(Slow Page)
This is how it looks like on another test development site:
http://i.imgur.com/5lwHxH2.png
(Fast Page)
Generating difference is 6 seconds.
As you can tell, in the slow site, everything is nested under layout/db_updates, but on the slow site, it's not.
The most time consuming call is
CONFIGURABLE:Mage_Catalog_Model_Product_Type_Configurable::getConfigurableAttributes
which is not called on the fast site. Instead it's just:
__EAV_LOAD_MODEL__
In var/cache files appear. Error Log doesn't log anything.
Does anyone know, how I could solve this?
Thank you very much!
EDIT:
What I have found so far.
/Mage/Core/Model/Layout/update.php
public function fetchDbLayoutUpdates($handle)
{
$_profilerKey = 'layout/db_update: '.$handle;
Varien_Profiler::start($_profilerKey);
Mage::log($_profilerKey, null, 'mylogfile.log');
$updateStr = $this->_getUpdateString($handle);
if (!$updateStr) {
return false;
}
$updateStr = '<update_xml>' . $updateStr . '</update_xml>';
$updateStr = str_replace($this->_subst['from'], $this->_subst['to'], $updateStr);
$updateXml = simplexml_load_string($updateStr, $this->getElementClass());
$this->fetchRecursiveUpdates($updateXml);
$this->addUpdate($updateXml->innerXml());
Varien_Profiler::stop($_profilerKey);
return true;
}
As expected is $updateStr empty and the call returns falls.
So I had a closer look on $this->_getUpdateString($handle):
return Mage::getResourceModel('core/layout')->fetchUpdatesByHandle($handle);
I found fetchUpdatesByHandle($handle); in /Mage/Core/Model/Resource/Layout.php:
public function fetchUpdatesByHandle($handle, $params = array())
{
$bind = array(
'store_id' => Mage::app()->getStore()->getId(),
'area' => Mage::getSingleton('core/design_package')->getArea(),
'package' => Mage::getSingleton('core/design_package')->getPackageName(),
'theme' => Mage::getSingleton('core/design_package')->getTheme('layout')
);
foreach ($params as $key => $value) {
if (isset($bind[$key])) {
$bind[$key] = $value;
}
}
$bind['layout_update_handle'] = $handle;
$result = '';
$readAdapter = $this->_getReadAdapter();
if ($readAdapter) {
$select = $readAdapter->select()
->from(array('layout_update' => $this->getMainTable()), array('xml'))
->join(array('link'=>$this->getTable('core/layout_link')),
'link.layout_update_id=layout_update.layout_update_id',
'')
->where('link.store_id IN (0, :store_id)')
->where('link.area = :area')
->where('link.package = :package')
->where('link.theme = :theme')
->where('layout_update.handle = :layout_update_handle')
->order('layout_update.sort_order ' . Varien_Db_Select::SQL_ASC);
$result = join('', $readAdapter->fetchCol($select, $bind));
}
return $result;
}
$result is expected an empty string.
$select looks like this:

Result
string(0) ""
The weird thing is, that in my fast test development, $result is also empty?
Really don't know what this all means!
EDIT2:
I noticed this when looking at the instantiated models using Magneto Debug:
MODELS
Resource Name Model Class Times Instantiated
catalog/category_flat Mage_Catalog_Model_Category 32
cms/page Mage_Cms_Model_Page 18
cms/block Mage_Cms_Model_Block 5
catalog/attribute Mage_Catalog_Model_Resource_Eav_Attribute 2
eav/entity_type Mage_Eav_Model_Entity_Type 2
core/url_rewrite Mage_Core_Model_Url_Rewrite 2
index/process Mage_Index_Model_Process 2
core/flag Mage_Catalog_Model_Product_Flat_Flag 1
customer/group Mage_Customer_Model_Group 1
But: catalog/product Mage_Catalog_Model_Product 9 is not shwon, even though there are displayed products, and which is instantiated in the fast shop.
