But I guess that should not adversely affect the driver. Anyway, with the patch performance was just good enough to let some NFS through. However, this certainly is no hardware problem because when using the driver from ports (net/intel-em-kmod) performance is perfect. Something is still very broken with the conversion of this driver to iflib. I just noticed that comment #34 just shows a merge to stable/12, but I am running releng/12.0. So I should probably merge this stuff and see how that works. -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
