Since th= en I see a huge difference in nfs cache misses, especially getattr-misses co= mpared to identical configured machines that are still on 10.3. When I do an= nfsstat -m the options are identical.=20 This leads too less performance and less happy end users. Is there any regre= ssion known? Any defaults that changed? Anything else I should know about th= at could lead to this behavior? I am grateful for any hint.=20 Niels=
