|

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,
|
