You don't mention which NFS server or NFS version you are using but for "traditional" NFS, this is by design. The NFS server is stateless and NFS server failures are transparent (other than time-wise) to the client. This means that once the server acknowledges a write, it guarantees the client will be able to later retrieve that data, even if the server crashes. This implies that the server needs to do a synchronous write to disk before it can return the acknowledgement back to the client. -- Peter Jeremy
