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