I had a chance to get some cheap gigabit ethernet cards and a switch the
other day with the thought that moving video files around would get a lot
quicker. Instead I find that I'm only getting maybe a 10% increase in
speed. My server box is using a D-Link DGE-530T with kernel module skge.ko
and my laptop uses the Intel e1000.ko for the built-in ethernet. The switch
is an Airlink 101 8-port gigabit ethernet switch. I get all the correct
link lights showing I have gigabit ethernet connections at all ends.
If I do an NFS mount and copy a large file from the server to /dev/null on
the client or if I scp a file between the server and client I get pretty
much the same results, about 11MB (that's bytes) per second. This is only
about 10% better than 100baseT ethernet. I know from previous experiments
that my hard drives and general system throughput can handle about
25MB/sec.
So any hints on how to get this to work faster, or am I seeing the results
of a marketing scam?
Are you using a PCI or PCIE bus? PCI has a bandwidth cap well under the
gigabit limit. So cards don't work well. You pretty much need gigabit on
the motherboard to get near full bandwidth.
