[drupal-devel] slow queries?

Hi there! Moshe alerted me to this page: http://drupal.org/admin/logs/pages?sort=desc&order=Average+page+generation+t... You will see that several search pages (but also others) took a very long time to generate (up to three minutes). While the overal effect of those few pages is probably low, I still think we should discover what causes it. I'd especially like to know why the maximum php executiomn time does not kick in. Can anybody enlighten me? Cheers, Gerhard
