No, on the uml-user list there are some reports NFS is faster than hostfs (= not=20 actual benchmarks, just feelings): I think that this can be true due to the= =20 super-optimization of NFS gone in for years; also it's difficult to optimiz= e=20 something when you cannot use inline functions for some things (i.e. the=20 distinction between userspace and kernelspace files).
