I'd agree that is somewhat drastic, and have passed the information on to the server vendor, however that doesn't change the fact that we have a client bug too: we should not be using expired creds. The client side performance problem was compounded by the fact that the RPCSEC_GSS destruction call was sent as a hard RPC call, and the fact that we impose the NFSv4 rule that we need to drop the connection before resending a request. -- Trond Myklebust Linux NFS client maintainer NetApp Trond.Myklebust@xxxxxxxxxx www.netapp.com -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
