FreeBSD 12.0 i386 . can run on either server A, B, or C . Builds ports, fetching distfiles from a shared directory on host A via = NFS. Result: - If the client is run on A or C, NFS between the client and server A runs = as usual. - If the client is run on B (i.e., NFS is done over the wire to machine A),= NFS has extremely poor performance, to the point of no throughput at all - The iSCSI provisioning from A for the client on B is running at normal sp= eed (i.e., the emulated machine itself sees normal disk performance) - When B was still running 11.2, NFS performance was normal.
