Bonjour,
j'ai demandé à OVH pour connaitre les raisons des lenteurs sur mon site
ils me répondent qu'ils ont des problèmes sur leurs serveurs en ce moment mais que ce n’est pas la raison pour mon site
ils m'ont donné un rapport et je voudrais savoir ce que je peux faire pour améliorer ça
ils me disent qu'il me faut optimiser les requêtes...
merci
