+Bonjour,
+
+Veuillez trouver ci-joint un rapport MySQL.
+Celui-ci permet d'identifier aisément si des optimisations MySQL sont possibles.
+
+N'hésitez pas à nous indiquer par mail ou ticket quelles variables vous souhaiter
+optimiser.
+
+Veuillez noter qu'il faudra redémarrer MySQL pour appliquer de nouveaux paramètres.
+
+Bien à vous,
+--
+Rapport automatique Evolix
