Debian Configuration :: Slow Transfer Speeds On SAMBA Share But Gigabit Speed On SCP

Feb 12, 2016

I'm having a strange problem with data transfers between systems. I have a file server + my desktop. Both are running Debian 8.3. I have a samba share running on the file server and I mount the shares on my desktop on boot via /etc/fstab

When I copy a file using the nautilus from my home folder (on my HDD) on my desktop to the mounted network location, my transfers start out at gigabit speeds 80MB/s-90MB/s for a couple seconds and then drop down to about 8MB/s

But when I terminate the transfer and then use scp to transfer the same file, I get consistent gigabit speed throughout the transfer. I am not sure what is going on.

Ubuntu Networking :: Gigabit Card Only Works On 100 MBit

Apr 14, 2010

I have bought two Asus NX1101 gigabit cards for my kubuntu box and ubuntu server box. The cards are automatically detected as eth1. However the speed is set to 100mbit instead of 1gbit.

ifconfig eth1 .....

I noticed that both lshw and ethtool claim that the card does not support 1000mbit. So changing the speed manually with ethtool doesn't work. In windows XP the card works as it should.

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:

CentOS 5 Networking :: On Board Network Card Refuses To Run Gigabit?

Jun 30, 2009

I've just set up a PC with CentOS 5.3 runing on near identical hardware to an existing 5.2 machine. Motherboard is Asus M2A-VM which I discover by chance generally works very well with CentOS. Ethernet is on board Nvidia.The older machine just did run gigabit speed without any intervention at all, rather to my surprise. The newer machine insists on running at 100 Mbit which is annoying as it is connected to a NAS through a gigabit dumb switch.

The obvious difference between the two is that ethtool on the older machine says that supported ports are TP, and so the port is TP. Whereas the newer machine says that supported ports are TP or MII and insists on running MII. I cannot change this with ethtool -s eth0 port tp. Perhaps not too surprisingly, mii-tool says that the supported speeds range up to 100 Mbit.

Ubuntu Networking :: Variable Download Speeds, Faulty Wifi Card?

Oct 12, 2010

I'm having a variety of problems getting a new PC working properly, getting a reliable wifi connection is one of them. Earlier today I upgraded to 10.10 using my wife's account and download speeds were frequently at a reasonable 800kbps at times. This evening my son complains about the slow speed and a test shows 133kbps download with 616kbps upload. My own PC connected by wire to the router works OK.

A couple of days ago this problem seemed resolved when I installed Wicd but didn't configure it. I thought Network-Manager would have been removed but was still present. However, a downloads test showed 6Mbps. After today's upgrade slow downloads have returned.

I'm currently using this PC with a wifi link to the router and am connected to the Forum. If I hover the mouse pointer over the N-M toolbar symbol a window opens saying-

Wireless network connection 'Auto MYESSID'active:MYESSID(67%) If I right mouse click on the N-M symbol and select Edit connection... the wireless window reports that I was last connected 3 days ago. My own PC's wired connection window says against Auto eth0 that I've never used this. Both these are untrue. I wondered if having a hidden ESSID doesn't help? I'm left thinking that the rt2500 based wifi card needs replacing. We're some distance from other houses.

Debian Installation :: Which PCI Gigabit LAN Card Is Lenny Proof

Feb 1, 2010

I'm giving up trying to install Lenny as a server. The netinstall won't recognise my realtek 8139 chipset on the PCI ethernet NIC. I've googled so much i'm freakin loosing it. The install fails while getting an IP adress via DHCP. So a new networkcard is in order. Why not go for gigabit lan then. Which PCI gigabit LAN card is 100% guaranteed to work with Lenny net install cd?

Ubuntu Servers :: Inserted Gigabit Ethernet Card - Now What To Do

Mar 3, 2010

I installed ubuntu server 9.10. During the install the onboard 10/100 land card was automatically installed and was used for updating packages. I just put in a DGE-530T gigabit ethernet card. I can see it recognized under lspci.01:07.0 Ethernet controller: D-Link System Inc DGE-530T Gigabit Ethernet Adapter (rev 11) (rev 11). It does not show up under ifconfig. The CD came with linux drivers. The readme talked about recompiling the kernel and a whole bunch of other stuff. Google was equally confusing. What do I do?

OpenSUSE Hardware :: 11.2 - Marvell Yukon Gigabit Ethernet Network Card 88E8072

May 12, 2010

I have a dual boot system (Suse 10.0 and Windows XP Pro) in my notebook. My notebook is toshiba m358, which has a Marvell Yukon Gigabit Ethernet Network Card (Marvell 88E8072) on it. My problem is this: in Windows XP Pro, the network card works well, but in openSUSE, the light on the network card does not turn on. I believe that there is no driver for the network card. I have tried several ways to solve this problem:

1. Download Marvell 88E8072's driver from "[URL]", whose name is "install_v10.85.3.3.tar.bz2", and then install it with following commands:

Code:
# tar xfvj install_v10.85.3.3.tar.bz2
# cd DriverInstall
# ./install.sh .....

Code:
# modprobe sk98lin
# WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/.
After I reboot the openSUSE, the light of network card is still off.

2. Follow "[URL]" to configure the Marvell 88E8072. It also does not work.

Ubuntu Networking :: Not Getting Gigabit Connection

Aug 24, 2010

I'm running a wired gigabit card using the atl1c driver. It works fine, but I don't get gigabit, only 100 Mbps. I have a gigabit switch and other Ubuntu machines on my network are gigabit. Is there any way this could be a software/configuration issue, or is the only likely explanation that my wires are of sub-par quality somewhere?

CentOS 5 Networking :: Trying To Upgrade To Gigabit

Feb 12, 2010

I am running CentOS 5.3.The NIC on my motherboard does not support gigabit, so I bought a gigabit network card. I installed the network card and configured it via system-config-network. Everything seems to work fine as long as I keep a cable plugged into the original NIC. The original NIC works just fine if it is the only one with a network connection, but as soon as I uplug the original NIC I can no longer ping nor connect to the server via the gigabit NIC.

The original NIC is eth0, the new NIC is eth1. Is there something I need to do to tell the system that eth0 is not required or something? I've never encountered an issue like this before...

Networking :: Transfer Rate For Gigabit Ethernet

Apr 1, 2010

We have a Linux box which acts a a file server. Currently, files and directories are exported using NFS.At the moment, we are a bit concern on its data transfer performance. FYI, we are using a embedded Gigabit Ethernet port on the file server. We ran a few simple write tests between NFS client (also utilizes GigE port) and the NFS server. In these tests, both NFS server and client are both connected directly to each other with a Cat5E cable. Unfortunately, the write/transfer speed results are not as per our expectation. It scores roughly about 11-12MByte/s, where as theoretically Gigabit Ethernet transfer rate is able to reach up to approximately 120MByte/s.I wouldn't expect to reach the theoretical max transfer rate (it would be great if we can , but I would appreciate if you guys can share with us in terms of the following :

1) What's the practical max data transfer rate which you guys managed to observe in a normal Gigabit based connection? What about jumbo frames configuration?

2) Is there any additional tuning/configuration we need to do within the OS to reach those practical max data transfer rate figure?

3) Does PCI-e / system bus plays a role in achieving this speed? For example, we are using the embedded GigE port and we heard some people says embedded ports are actually sharing the system bus and resources with other devices, which might adds into performance issue. Correct me if I'm wrong.

4) Does converting to Cat6 cabling will guarantee an increase in the data transfer performance?

5) In the future (once we are clear on how much single GigE transfer rate we can go) , we are looking into doing bonding since that the NFS server's shared directory/volume read-write speed is way much higher (i.e 400-600MByte/s). Will bonding allow us to achieve higher NFS read/write speed? What are the bonding modes best used for this purposes? Appreciate if anybody who has experience in doing bonding for NFS can share their experience.

Ubuntu Networking :: No Speed Improvement With Gigabit NIC / Switch?

Jan 13, 2010

I recently upgraded a server's networking card to a Gigabit NIC, and got a hold of a Gigabit switch (Here's a link) in the hopes of increasing my network performance - however, I'm getting around 10 MB/s throughput now, which is exactly what I used to get with the old 10/100 switch & NIC. The new switch recognizes both computers as Gigabit (the other machine has always had a Gigabit NIC), and both computers say they're gigabit - I've found various sites around the interwebz recommending tweaking some TCP/IP buffer settings, which I have tried to no avail. I also saw that hard drive speed is usually the limiting factor. According to "hdmarp -t", the server HDD (definitely the slower of the two) is:

Code:
Timing buffered disk reads: 226 MB in 3.00 seconds = 75.26 MB/sec

So that's obviously not my issue. The cabling is CAT6 - I ran it myself, but if I'd mis-wired the end connections, wouldn't it just not work at all? I admit, I bought cheap NIC's (I'm not going for like 124.9 MB/s throughput here..), and I didn't expect them to be stellar, but I certainly expected the speeds to improve. I'm moving files from a server running Ubuntu 9.04 to a Windows machine - I've tried both my Samba shares on the server and an SFTP transfer: they both have about the same throughput.

Networking :: Gigabit Switch Causing Network To Freeze?

Dec 30, 2010

We have an old Zonet 10/100 switch in our home network that locks up whenever there's a power glitch longer than about a microsecond. (OK. It's not that bad but if the lights flicker, I usually end up going down to the basement to see if the switch is hung.) None of the computers or peripherals are affected by the glitches, BTW. Power-cycle the switch and everything starts working again. After putting up with this for months I finally picked up a Netgear 8-port 10/100/1000 switch to replace the Zonet. Unfortunately, when the Netgear switch is in the network, everything slows to a crawl before completely freezing up. Pinging other systems barely worksname would not work.Pinging another system by its IP address worked a little but packet losses of 70%-80% were the best I saw. At first. Then it gets to where the loss is 100%.

All systems were rebooted after the Netgear switch was inserted into the network. The systems that were capable of gigabit connections autosensed the new switch and set their port speed accordingly. And that's about all that works when the Netgear switch is present. (The Zonet is back in the network now.)One thing I have not tried is forcing the port speed on the gigabit-capable systems to 100Mb and re-inserting the Netgear switch into the network to see if the problem if due to running some of the ports at 1000Mb.The systems on the network are running various versions of Linux (with different kernel versions, of course). Most are due for upgrades to get them current but I was planning on hitting the systems that had gigabit-capable ethernet interfaces thinking that a.) 100Mb speeds have been around forever and no problems have been seen when everything was running at 100Mb in the past and b.) the gigabit support for the older kernels should be better (one system only supports an MTA of 1500 max at 1000Mb).

Networking :: Huge Packet Loss On A Gigabit Link ?

Dec 28, 2010

I have a following configuration: 4 PCs (say, A, B, C and D), running Ubuntu or Debian, interconnected using a gigabit switch, which is connected to the Internet. Two machines (say, A and B) also have a direct private connection between them (provided by another pair of NICs).

Now, when I test the connection performance with iperf, the results vary. The private connection between A and B performs well - about 930Mbps using iperf's UDP test. Between C and D it is about 800Mbps which I find tolerable. Packet loss when running these tests is negligible.

However, when I run iperf between any of {A,B} and {C,D}, the performance significantly drops as there is a huge number of lost packets.

For example, here is the result of testing between A and C:

Why is there such a large number of packets which are generated, but lost somewhere?

A<->B private link works fine, so system level parameters on both A and B are correct. Furthermore, C<->D works ok, so I guess I shouldn't blame the switch.

Is there a per-NIC configuration that I should check or it smells like a hw problem? Problematic NICs on both A and B are of the same type - Allied Telesyn AT2916T.
