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?
