Si vous proposez un autre outil qui peut revenir en arrière requêtes à des vues ou des modules utilisés, il serait utile; pourvu si une telle chose existe. Si le regard sur les requêtes frappe un accord, merci d'écrire un commentaire.

Much Merci ..

Answer 1

Je ne vous inquiétez pas trop au sujet de ceux qui se produisent qu'une seule fois. La plupart est juste SELECT * FROM big_table qui est probablement fait par un administrateur. Je ne suis pas sûr de ce qui irait chercher toute la table de session, ce qui n'est pas très utile.

Quoi qu'il en soit, les autres requêtes qui se produisent plus d'une fois, est très probablement généré par des vues:

LEFT JOIN term_node term_node_value_0 
    ON node.vid = term_node_value_0.vid AND term_node_value_0.tid = N 

Faire 20 de ces jointures va ralentir toute requête, qui est aussi la raison pour laquelle il ressemble à vue. Les vues font des requêtes génériques sans savoir ce que vous voulez vraiment faire. Donc, il peut faire des hypothèses, c'est pourquoi il peut dans certains cas faire des requêtes folles comme ça. Le seul correctif serait de personnaliser le code ou seulement la requête. Les vues ont du mal à faire de bonnes requêtes sur les termes quand les choses sont un peu complexes, car les termes ont une relation de 1 à plusieurs (un terme peut être associé pour faire des nœuds).

Donc, vérifiez les vues que vous avez, vous pourriez être en mesure de gérer cela avec le cache à partir de l'interface utilisateur des vues.

Answer 2

Installez et activez le module devel.

Accédez au paramètres du module la page (example.com/admin/settings/devel) et vérifier

• info requête Collect
• Affichage requête journal

Cette rédigera chaque requête pour une requête de page au bas de la page et vous dire la fonction qui a écrit la requête (la colonne where). Le nom de la fonction est le moduleName_functionName.

Et googletorp est exactement correct.

Answer 3

Nodewords 1.14 devrait fonctionner mieux, la mise en cache interne a été ajoutée afin qu'il ne réexécute pas la même requête comme il le faisait. Le principal coupable semble être la requête de page de termes de taxonomie de Views, qui vérifie par défaut neuf niveaux de récursivité pour identifier le contenu correspondant. Vous devriez changer l'argument "profondeur" de la vue à la profondeur de la hiérarchie maximale que vos vocabulaires (catégories, balises, etc.) utilisent réellement, et si vous n'utilisez pas de hiérarchies de termes, vous devriez définir la profondeur à 0 ou mieux , supprime entièrement le terme id + arguments de profondeur et remplace le par l'argument de base id d'argument.
