No Gigabit with r8169 module

No Gigabit with r8169 module

[Dennis]

Hi!

I am trying to build up a gigabit network with the following equipment (all 
from Netgear):

- Laptop: GA511 PCMCIA Gigabit Adapter
- PC: GA311 PCI Gigabit Card
- GS605 5-port Gigabit Switch

Both PCMCIA and PCI Cards are running with the r8169 driver. The PC as the 
laptop are installed with Suse 9.3.
The Switch has dual color support on the connection LEDs and both ports (the 
one connected to the PC and the one connected to the Laptop) are showing that 
they are connected to gigabit ethernet cards. 

What I tried to do is to copy a folder from the laptop to the PC, which size 
is about 6.1 GB. I am using KDE 3.4 and the konqueror with fish-protocol. The 
copy dialogue says that this wold take about 2.5 hours with a average of 850 
kbit/s. This is quite too slow for gigabit. 

Just to make sure that I didn´t make a hardware connection mistake, i tried 
the connection with Windows XP and there, a folder which size is about 2.1 GB 
takes about 10 minutes to copy - seems like gigabit is actually working with 
all cables I am using. Another point was that suse could be the scapegoat, so 
I used knoppix to test the connection under linux again. I got the same slow 
speed here. 

The laptop has three network interfaces, but I switched all of except the 
gigabit  card (ifdown <device>), so no mistake there possible from my point 
of view (correct me if I am wrong here).

Now I wonder if this is due to the driver or did I do something wrong? I would 
be happy for any help that gets me further to get my gigabit running. If 
there are any more details I have to supply, please ask me.

Yours,
Mike

- Which kernel are you using ?
- Can you try plain old scp -c blowfish $BIG_FILE in a text console (i.e.
  outside of X) and report the transfer rate ?
- If it still sucks, can you try 2.6.13-rc6 ?
- Please send:
  o complete dmesg after boot
  o lspci -vx
  o lsmod
  o cat /proc/interrupts + vmstat 1 during transfer
  o ethtool ethX

Do not hesitate to use bugzilla.kernel.org.

It means 3~4 Mo/s. Unimpressing.
