Ok, so I straced the same file copy twice, first one with the slow process, second one after a kill HUP command.
Then I made a diff and it appeared that, in the first one, there are a lot of "error packet at smbd/notify.c" when doing a "kernel_ckeck_notify"... I don't know what it means but I hope that you will understand it and that you will be able to help me :-)) (It is quite critical in my company...)
