DB queries profiler:
Magento provides an ability for developers to track database queries. For this purpose you should use a built in DB resource profiler. It can help you to inspect database queries, detect the longest query, detect the slowest query, etc.. Here is a small example on how to use a DB profiler for your own needs :

$profiler = Mage::getSingleton('core/resource')->getConnection('core_write')->getProfiler(); foreach ($profiler->getQueryProfiles() as $query) { $queryTime[] = $query->getElapsedSecs(); // Get the query execution time $queryRaw[] = $query->getQuery(); // Get the query text }
