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.
