Soit le dump n'est pas pris au bon moment, soit la 'lenteur' est due à un facteur non-applicatif (exemple : full GC, base de données, IO, …)</SPAN><BR /><BR /><SPAN>A noter que votre machine swappe de manière significative. je vous suggère de réduire la taille de la heap, et de réduire la swappiness du kernel (sans doute par défaut à 60, 10 serait plus raisonnable).</SPAN></BODY></HTML> Tue, 11 Oct 2011 13:04:48 GMT https://connect.hyland.com/t5/alfresco-archive/lenteurs-apr%C3%A8s-3-mois-d-utilisation/m-p/179291#M132421 rguinot 2011-10-11T13:04:48Z
