Titre du sujet : Re: Surcharge serveur
par escrime-info sur 20/09/2013 16:23:12
Je relance le sujet car mon hébergeur continue à me demander, à juste titre, d'optimiser mes requêtes SQL.

Contenu du fichier slowlog !

C'est donc newbb 3.08 qui est en cause. Comment éviter de surcharger le serveur mutualisé ? J'ai plus de 300.000 posts dans le forum...
Merci à vous !
