I have 3 boxes, each with two nics. One nic for the private network and one for the public network. The private network is all on the same vlan. All 6 nics are on the same switch. All connections are 1000tx Full Duplex. I will call the servers Box A, Box B, and Box C. When i FTP data between Box A & B i get abou 25MB/sec. When i FTP data from Box C to Box A or B, i get about 20MB/sec. When i FTP data from Box A to C i get 10MB/sec When i FTP data from Box B to C i get 200KB/sec... Can anyone suggest why i might only be getting 200KB when transfering data from Box B to C but not when transferring data from Box A to C? I tried installing ubuntu to see if the problem was still there and it is not. I can FTP data from Box A or B to box C at 10MB/sec, still not the gigabit speeds i should be seeing but not the 200KB/sec i am getting with freebsd. I logged into my switch and it reports that the ports are 1000tx full duplex, the same as what freebsd is reporting. The switch & freebsd also report no errors. I really dont know what to do. Nothing anywhere reports showing a problem but obviously there is a problem somewhere. I've tried drivers 1.9.5, 1.8.4, and 1.7.3. If i use 1.8.4 or 1.7.3 i get 50KB/sec transferring data from box B whereas if i use 1.9.5 i get 200-300KB sec. I should be getting like 50MB/sec ;( Any help would be grateful. Or, maybe someone could put me in touch with the person responsible for the intel nic drivers and i can work with them on resolving this issue? Thanks in advance.
