Slow transfer between ubuntu 12.04 and network hdd

[joehc]

Hey guys

When I transfer a file from my ubuntu machine to my network hard drive it is extremely slow, like 100 kb/s.

My machine has ubuntu 12.04, and has a wired connection to my router. My extern hard drive is connected to my WD TV LIVE which also is wired connected to my router.

The funny thing is that, if I switch to Windows, the speed is just fine. And when I used ubuntu 10.04 there were no problems with the speed.

I have install samba, and even if I mount the network hard drive or just use network explore in nautilus it is the same slow speed.

Can anyone help me?

Yep, they appear to have broken something.
I have 2 other pcs at home with 10.?? and 11.04 installed and all mount a vfat NAS drive. I add a line into /etc/fstab using smbfs. Reasonable response fro the server with the older systems.

Installed 12.04 on 4 year old Dell Vostro.
12.04 is very slow talking to the NAS samba server. Even the file manager is slow in just showing me the files in a directory. The server hosts all my Thunderbird email folder so that any machine can get to them and this takes about 30 seconds to just open and then is very slow retrieving files. I tried changing the fstab driver to cifs but its the same thing.

Any help would be appreciated.

So am I !!

My 12.04 Ubuntu Server has really slow data transfert.

The network interface works great up to 1.6 MB from the net.

But the network share (with samba and nfs) doesn't provide a better transfert rate than 30 kb/s from server to client.

But I can send a file from client to server at 11 Mb/s (from Samba) ....

I'm about to install a fresh debian to check if the problem also exists....

I've just installed Debian 6.05

Same issue with Samba :
server to client = 50 kb/s
client to server = 10 000 kb/s

(I don't try nfs share yet ... )

#WTF ?

Any news on this matter?

For me it was a PEBKAC applied to network...

PEBCAS : Problem Exists Between Client And Server

When I upgraded my server I also add some ram modules and do I exchanged some cable...

My bug was a deffective RJ45 cable ... I can notice before because it was plugged on another read-only machine.

The only thing I have done before changing the cable is to downgrade my network driver realtek r8169 to r8168, by adding a new package repository taht old propretary firmware (nonfree)(debian repo, since I have migrate to debian)

To check if your network adapter is a realtek, you can type this :

lspci | grep r816

Good Luck !

Well, I get this:

Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)

So I should find another driver version?
