Slow internal networking with Linux?

[Heeter]

Hi all,


wondering why my Linux box is really slow transferring files to Windows Server as compared to other Windows XP workstations.

All the towers (Server, linux, XP machines) have the same network card: Intel 1000GT Pro PCI

It is the only network card that I use on all my machines, even if it has onboard port.

Is there anything that I can do to "speed up" the file transferring process from/to this linux box?


Thanks,

Heeter

Hey all,

still having terribly slow issues with my internal network with my linux machine.

Still haven't figured it out.


Heeter

[j79zlr]

Sorry Heeter, forgot about this thread. Post the output of ifconfig -a If you have the MTU value set to something higher than 1500 it can cause problems with the e1000 driver.

[Heeter]

Could it be that this is happening because I disabled the IPv6 in the network manager?



Let me know what you think,


Helder

[j79zlr]

Everything looks ok so far, how about the output of dmesg | grep -i eth

[Heeter]

Thanks for the help J,

What do you think about the IPv6 that I disabled?


Helder

[j79zlr]

e1000: eth0: e1000_watchdog_task: NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX

Looks like its up and running at its full speed. I don't think ipv6 should affect you at all. Are the speeds slow from the other pc's to your linux box, or just the server. Have you checked firewalls and tested with them disabled? Any reason why the connection is bridged? To be perfectly honest I am not really sure what is causing your issue.

[Heeter]

Bridged is probably the VMware Server that I installed on the linux workstation.

Other than that I wouldn't know why.

I have only tested between that server/linux

All firewalls are disabled throughout the internal network.

Maybe I should remove the vmware server app and retest.



Helder

[Heeter]

Might the specs of the machines account for anything?

XP: P4 3.2E, 2500megRAM, OpenSuse: AthlonXP2000+ 1.6gig, 1000megRAM

I just tried a 750meg file transfer from server to each machine, XP machine: 50 secs, Linux box: 4:50


Oh well,


Heeter

[j79zlr]

That machine is powerful enough, it wouldn't be the cpu as the bottleneck. Even those speeds to the XP machine seems a little slow for gigabit. That comes out to around 120Mbps, I would think you should be seeing about 500Mbps at the least. Is the router gigabit?

[Heeter]

Hmmm, good point, maybe it's my hardware structure.

Server/Linux/XP are not directly connected to the router, they are connected to a Dlink Gigabit Switch, then the switch is connected to the Netgear Router

Maybe my hardware needs upgrading,

Your Thoughts?
