Ubuntu Networking :: Slow File Transfers (FTP, SCP) With Intel Gigabit Or Atheros WLAN?

Nov 16, 2010

I just installed ubuntu as my primary OS, but I have the disk with XP on it and I don't want to go back, but I need faster network connectivity. I have a T60p with Intel Gigabit jacked into my Gigabit router which also has my desktop (running XP) and my NAS. If I FTP files from my NAS (or SCP), I get transfer speeds around 250-500 KB/s (which is not very fast). On this same switch, from my XP desktop I get transfer speeds around 12 MB/s. I get the same speeds using my 802.11n card (Atheros) as with the ethernet NIC (250-500 KB/s).The drivers for the ethernet card and the atheros card are e1000e and ath9k respectively.I have disabled IPv6. Since the problem occurs using either interface, I am just going to concentrate on fixing it for the Ethernet interface (since I believe it to be a systemwide problem).

Code:

skinnersbane@albert:~$ sudo ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full

[code]....

Clearly my card is running at Gigabit, but why the bad transfer speeds? I am using filezilla for FTP (technically FTPES). I closed every other program. My CPU utilization does seem high and I wonder if this is part of the problem. I had no problems with throughput using either interface in Windows XP just one week ago.

Networking :: Ethernet Intel Gigabit Controller Is Broken Or That Atheros Driver Is Missing?

Apr 21, 2011

I have an ASUS P5Q PRO motherboard with an integrated Atheros AR8121/AR8113 PCI-E Gigabit Ethernet Adapter.I installed Ubuntu 10.04 "Lucid" 64bit Kernel version 2.6.32.21 I have read that the driver isn't in the kernel, but there's a strange thing :

First if I try to run lspci from command line it doesn't reports Atheros Ethernet Controller.

Second If I try to run lshw -C network from command line it doesn't reports Atheros Ethernet Controller.

Third if I run ifconfig it only returns my loopback address.

Can I suppose that my Ethernet Intel Gigabit Controller is broken or that Atheros driver is missing?

Networking :: Slow File Transfers Using Samba?

Feb 2, 2010

I am running Samba on a debian Lenny box on a wireless home network. I find that file transfers to the samba share are very slow. It takes over a minute to copy a 40MB file to the linux box, but only 20 seconds to copy the same file to a windows XP box on the same network.

Anyways, I could use a little direction on how to proceed with this, I'm really not sure where to start,

Ubuntu Networking :: Atheros Gigabit Controller Stuck At 100 Mbps?

Apr 18, 2011

I'm using Ubuntu Server 10.10 64 bit and am trying to get my Atheros AR81xx gigabit ethernet controller to use 1 gbps.I have 2 ethernet controllers, one's a linksys 100 mbps (which is connected to the router which goes to the internet) and the other is the Atheros gigabit controller that is connected to a Windows desktop that has an NVIDIA gigabit ethernet controller (for faster file transfers with a gigabit connection) I've ruled out that the problem is with the desktop as I plugged the windows PC into my macbook (which has a gigabit controller), and both the macbook and desktop report a gigabit connection.

I plug the windows desktop into the server and I only get 100 mbps. I am using a Cat 6 patch cable. I've tried several methods with ethtool to force it into 1 gbps mode, but none work. I've tried using a different cable. no change. I've tried making windows force a 1 gbps connection, didn't have the option to in the driver configuration. Only 10/100 configs. the commands I've tried in ethtool

Code:

ethtool -s eth0 speed 1000

Reports no error, but no effect. I've tried forcing off auto negotiation (I had a hunch it was causing the problem)

Code:

ethtool -s eth0 speed 1000 duplex full autoneg off

I get this

Code:

Cannot set new settings: Invalid argument
not setting speed
not setting duplex
not setting autoneg

I tried each setting individually, and autoneg won't set, the others will (but not do anything)

Ubuntu :: Slow File Transfers On 10.10?

Oct 30, 2010

Has anyone else noticed that file transfers on Maverick are significantly slower than on Lucid? A review of Maverick on Tom's Hardware finds that it is considerably slower. My own test says: On 10.10, file copy between two NTFS drives maxes at 30 MBytes/s; on 10.04.1, the same operations clock in at 40 MBytes/s. Both drives are capable of rw speeds of 70-90 MBytes/s, which I got on WinXP, and hdparm's cached read results back that up.

why file transfers are so slow, and especially why Maverick is even slower than Lucid?

Fedora :: File Transfers (cp, Mv And Rsync) Slow System Tremendously

Aug 24, 2011

When ever I transfer large files using cp, mv, rsync or dolphin the system will slow down to the point that it's unusable. It will sometime hang completely and not accept any input until the file is transferred. I have no clue what could be causing this problem but I know it shouldn't be happening.I am using Fedora 15 (2.6.40.3-0.fc15.x86_64) with KDE 4.6. have a Phenom II 955 processor, 6 GB of system ram and the OS and swap file is on an 80 GB SSD. Copying files in the SSD doesn't cause any problem, but moving files between my other two large HDDs causes the extreme slow down. Using htop I can see that my system load jumps to between 3 and 4, but my RAM and CPU usage stays low during the transfer. Here are two commands that take about 10 mins to run and make the system unusable while it's running. It usually transferring around 2-20GB worth of data during the transfers:

cp -a /media/data.1.5/backup/Minecraft/backups/* /media/data.0.5/backup/Minecraft/backups/
rsync -a /media/data.1.5/backup/ /media/data.0.5/backup/
/media/data.1.5/ is the mount point for a 1.5 TB internal SATA drive, and /media/data.0.5/ is the mount point for a 500 GB internal SATA drive.

Ubuntu Servers :: Samba Configuration - File Transfers Between The Machines Are Extremely Slow

Nov 1, 2010

1. When I'm not logged into the server, only the shares are visible on my Windows computer. Clicking on the share folder displays an error message. As soon as I log in at the server, the files within the shares become accessible on the Windows box.

2. File transfers between the machines are extremely slow. Watching the system monitor, there's a brief burst of network activity followed by 10-30 seconds of nothing...on a gigabit network, the effective transfer rate is ~120kbs. There's no other network activity going on that would account for this behavior.

Fedora Networking :: Intel Gigabit Card Only Connects At 100Mbps

Jan 24, 2009

I recently swapped out my old network switch (10/100) for a Netgear GS105 gigabit switch. With the exception of my Fedora 10 laptop all the rest successfully connect at gigabit speeds. But my laptop (with an Intel Corporation 82566MM Gigabit Network Connection (rev 03)) will only connect at 100Mbps. If I look in the logs for my network card here is what I get:

Networking :: Slow Transfer Rate Between 2 Gigabit Devices?

Mar 2, 2011

I am struggling trying to understand the reason for a fairly slow data transfer rate between two machines. ( tried point to point and also via a 1 gb switch )
One is nfs/http/ftp server ( with raid1 and lvm on top ), the other one my desktop pc. Both OS with default options, no changes to kernel in proc or other sort of thing.

Hardware is full recognized and perfectly working: The server has 4gb ram, Intel Core 2 Duo CPUE6850 @ 3.00GHz, 1000Mb/s NIC card and Lucid 10.04 64 bit, 250Giga Hard disk. The client has 3gb ram, Intel Core 2 CPU 6320 @ 1.86GHz, 1000Mb/s NIC card and Ubuntu Maverick 32bit , 150Gb Hard disk.

Raw data is good:

Fedora Networking :: Slow Wireless With Atheros AR9285?

Nov 3, 2010

I'm facing problems with Fedora13 and the AR9285 wifi card... the connection is just too slow, and the wired connection works fine. I just figured out that a lot of VAIO users (so am I) were in the same situation, and solved their problem by downloading ath9k drivers from linuxwireless.org. Fine, I did it! That's what I found :

Quote:

Building and installing
cd /path/to/compat-wireless-2.6.32-rc5
./scripts/driver-select <driver-name>
make
sudo make install

...but make is looking for source files in /usr/src/kernels/2.6.34-7-61.fc13.x86_64/build/ , which doesn't exist! The /usr/src/kernels/ folder is just empty. I also found something about the fact that Fedora13 didn't came with kernel's source files... So how can I install that driver? (I didn't find the package via yum...)

Fedora Networking :: Having Slow WLAN On 15?

Jun 16, 2011

I installed Fedara 15 yesterday. I was running Fedora 13 before. Since I did the fresh install, my wireless network runs really really slow, i.e. a few KBs every 30 seconds whereas it ran at full speed in F13. I couldn't find the reason for it. I now tried the live-CD for Fedora 14 and it runs at full speed out of the box (whereas F15 is slow even with all updates installed).
Does somebody know a solution?

Laptop: Lenovo X201
Network Card: Ultimate-N 6300

I gathered uname, iwconfig, lspci and dmesg output for both, Fedara 15 and Fedora 14. But as the number of links is limited here in the forum they're all linked here: [URL]

Ubuntu Networking :: Large File Transfers & How To Set Up A Netbook Desktop Combo

Jul 11, 2011

I tried using ssh between my netbook and desktop, but it was going to take around 30 hours to transfer 39GB over the home network. Also SSH is very sketchy and often drops connections.I've been messing with it all day and I'm quite frustrated.What I'm looking to do is use my netbook as more of a primary computer and the desktop as a storage computer. Not quite a server, because I'd like to still keep a GUI on it. I'd like to be able to keep my music and movies on the desktop and stream them to the netbook (SSH sucks for this, always drops connections). I've already set up the web client for Transmission bit torrent client so I can torrent on a machine that's almost always on and connected.

Is there a better setup for all of this? I like the netbook because of the portability; I like the desktop because it's always connected (for torrents) and it has a larger storage capacity. It would be mainly used around the house. I would like to back up a file or two while abroad, but I'm not looking to stream music while I'm across town or anything.

Ubuntu :: Embeded - Nas From Usb Stick Slow Transfers

Nov 21, 2010

With Ubuntu 10.10 server installed on an
- AMD Athlon II X2 235E CPU AM3
- 2GB DDR3

Installed on a software raid 1 of 16 GB usb sticks that can sustain 24MB/s read and 13MB/s write rates
running
- ssh
- zfs-fuse installed from apt
- samba

With the zfs using the sata II controller, with a 2TB, 1.5TB and 500GB in a raidz1 (I know, it's uneven, I'll be changing them all to 2TB once I get the data off those drives).

However I'm experiencing a REALLY REALLY exceptionally slow zfs performance of only 600KB/s transfer rate even when using the command:

To test. CPU usage is only at 25% (with dedup=on) however I notice that the usb sticks are regularly transferring data during this write to the zfs pool. Also when doing a zpool scrub it completes 9.6GB of scrubbing in well under 2 minutes. Admittedly it shouldn't actually be doing much as no data was changed by me while the 3rd drive was unavailable.

I'm thinking that there is some data being temporarily saved to the main system drive (usb sticks) and then transferred to the pool, and this is causing a bottle neck. Note both 16gb usb sticks are plugged in to the same usb 2 host controller, but the combined write bandwidth of those sticks is not enough to saturate a usb2 bus.

How to track down this bottle neck?

Networking :: Large File Transfers Start Fas Then Drop To A Crawl?

Jul 19, 2010

I need to transfer 330G of data from a hard drive in my workstation to my NAS device. The entire network is gigabit and being run with new HP procurve switches. All machines have static IP addresses. The NAS is a Buffalo Terastation PRO which has the latest firmware, is set to jumbo frames, and has just been upgraded with 4 brand new 500G drives giving us a 1.4TB raid 5 setup. My workstation is a dual Quad core xeon box running on an Intel S5000XVN board with 8G of ram. My OS is Ubuntu 10.04 x64 running on a pair of Intel X25 SSDs in a raid mirror. The data drive is a 500G SATA drive connected to my onboard controller. The file system on the SATA drive is XFS. This problem was ongoing before I got my new workstation, before we had the GB switches, and before the NAS got new drives. When I transfer a small file or folder (less than 500M) it reaches speeds of 10-11 MB/sec. When I transfer a file or folder larger than that the speed slows to a crawl (less than 2MB/sec). It has always been this way with this NAS. Changing to jumbo frames speeds up the small transfers but makes little difference in the big ones. I verified with HP that the switches are jumbo frame capable.

Ubuntu Networking :: D-link DWA-552 Master Mode On 10.04 - File Transfers Or Bandwidth Consuming Processes

May 20, 2010

after successfully configuring the dwa-552 to work in master mode in ubuntu 10.04 (ath9k driver) I ran some file transfer tests. The download speed is very good (~50mbps) but the upload speed spikes at about 10-20mbps for the first few KB and then it's nonexistent (0-1kbps). This only affects file transfers or otherwise bandwidth consuming processes. Normal web browsing or ssh is not affected. After running a speedtest of my internet connection which is routed through the AP I could upload to the internet with 1mbps which is my inet connection maximum so apparently this is not affected. Tried the same file transfers with netcat to eliminate any other factors and had the same problem. dmesg and hostapd debug did not report anything unusual

OpenSUSE Install :: 11.4 - "Atheros Communications L1 Gigabit Ethernet (rev B0)" Wasn't Recognized

May 5, 2011

having used SuSE Linux ever since the April 1995 release, I thought installing 11.4 would be a straightforward task. Since it wasn't, I'm summarising here my experience. My PC is built around a 3-year old Asus P5B-plus mainboard, i.e. certainly not brand-new hardware.

1 - on installation, my "Atheros Communications L1 Gigabit Ethernet (rev b0)" wasn't recognized, so I had to "modprobe atl1" from one of the consoles available during installation. That worked but the installer didn't pick up the fact that network was now available.

2 - after completion of the installation, online-updating for the first time and installing the nvidia driver for my "nVidia Corporation G71 [GeForce 7300 GS] (rev a1)" the KDE desktop showed the "blank desktop with mouse pointer" syndrome. Googling yielded that desktop effects had to be disabled in the kwinrc configuration file.

3 - logging in today after an online update, firefox (MozillaFirefox-4.0.1-0.2.2.x86_64) segfaults on start-up while loading the default website (opensuse.org). firefox will run in safemode but it won't run in normal mode, even with all add-ons disabled.

Now I don't have a useable system after a couple of hours of trying. Fortunately, I have a working installation of openSUSE 11.2 but I believe that updates for that distribution will be stopped shortly.

Fedora Hardware :: Intel Gigabit Ethernet(e1000e) Broke On 2.6.35 Kernel / Resolve This?

Nov 8, 2010

Just a heads up to others. There is a kernel regression in the 2.6.35 kernel with regard to, some but not all Intel Gigabit ethernet adapters using the e1000e driver. After an otherwise successful upgrade from fedora 13 to 14, no ethernet connection could be made while using the upgraded 2.6.35 kernel that comes with fedora 14. The 2.6.34 fedora 13 kernels work fine and were fortunately still available after the upgrade.

I have personally seen the identical malfunction on all 2.6.35 kernels I've tried with both Arch and Aptosid and have seen similar reported problems on the Gentoo forum. In each case, going back to a 2.6.34 or upgrading to a 2.6.36 kernel solved the problem so this is almost certainly a kernel issue. My onboard Intel Gigabit ethernet adapter is:

$ lspci -vv | grep Ethernet
00:19.0 Ethernet controller: Intel Corporation 82566DC Gigabit Network Connection (rev 02)

I believe the intel ICH8 chipset motherboards are the ones primarily effected.
