Dump writes to these drives at about 4mbps. To conserve resources I have been trying to dump to the same model drive on a remote machine using the : notation. When I do this dump writes at about .5mbps. Both machines are on dedicated 10bt switched connections and dump is definitely not taxing the 10bt connection. Both machines are 266Mhz which I have seen easily fill a switched 10bt connection. Neither machine is working particulary hard independent of the dump. I have tried replacing the 3COM 3C905 Fast Etherlink XL PCI with the Intel EtherExpress Pro 10/100B because I have had NFS problems while using the 3COM card. It appears the the default block size for dump is 1024 (as opposed to 8192 for NFS) so it I didn't think this would work, but I had the cards... With typical disk capacities of 4-9Gb dumping a drive at this speed can take over a day. Is this expected behavior? Is there a solution to this problem? What is the bottleneck?
