Hi there I have a problem with my XBMCBuntu machine.

I have a XBMCBuntu machine that holds all my HDD's and is connected to my TV.
If I move a 120MB file to my wifes machine it will take about 5sec ~11MB/s
If I move the same file from my machine to my XBMCBuntu machine it takes about 5min ~500KB/s
If I copy that same file from the XBMCBuntu machine it takes about 10sec ~6MB/s
This is a test I did 2days ago.
And I have mapped the drives of the XBMCBuntu machine in my computer, and it sometimes take a long time
to look trough the folders.

All machines are connected to a 10/100/1000 switch, and all the machines (3 of them) should be 10/100/1000 capable

If I download a ~200MB video trough utorrent I will get the video in few minutes, but it will stay at 99.9% for a long time
or until i've stopped it, force checked, rinse and repeat it couple of times.

I used a program called Lan speed test (lite) to check the connection.
I made a 100MB package to send to the XBMCBuntu machine, yesterday it went to 53MB of the package in few secs, then the speed dropped and
it took few minutes to send the rest of the package.
Just earlier I did it again, 100MB file, it jump right to 11MB then about 2 min later it stopped around 18MB and gave me the error "Error while writing data to test file!"

I restarted the machine and send the same package with the Lan program, waited for like 15 minutes until the program stopped responding.
I tried it again and used just a 20mb file, it got written in just 2sec. then the Lan program stops responding and
shows the status "Writing Data...Done: Waiting for the file to close"

This problem only started to occur maybe 2 weeks ago, and it's been slowly getting worse and worse, now I
cant move files to it, because it takes for ever.

Any one that could help me with this problem?

Usage on my disk's
Code:
playman@xbmc:~$ df -Th

Issue writing a lot of data to the hard drive rather than an ethernet problem?
I would try an extended read/write stress test on your hard drive to see.

Thank you for the reply.

How would I do that on a linux machine?

But which HDD should I test?
as I have 3 of them
1 for the system
and 2 for storage

And i'm getting poor transfer speed on both storage disk's, about the same speed, so it
can't be HDD problem? right?

Mmmmm yes, less likely to be HDD if both storage drives are affected. I'm not a Linux expert so could be miles off, but given that smaller files seem to be unaffected I wonder if it is swapfile related? i.e. for larger file buffers the system is attempting to buffer to a swapfile but failing. In that case the problem would be with your OS drive (assuming that is where the swapfile is located) or your swap setup.
Either way, this link should give you enough help to be able rule it out.

Don't have knowledge of Linux specific HDD testers. I would typically use a Hirens boot CD and something like HD tune to test hard drives.

If you want to test network speed a program called iperf can do that. Packages are available for Windows and Linux.

Linux: http://sourceforge.net/projects/iperf/ (Though it's very popular and might be available through your typical package manager like apt-get)

Windows: http://www.iperfwindows.com/


For testing drives speed on Linux, hdparm is one option.

Linux: http://sourceforge.net/projects/hdparm/ (Again, check with your package manager first as this is also very popular)

How-to: http://www.cyberciti.biz/tips/how-fast-i...-disk.html

I would test all drives.

It could be the controller, or even the file system used. It is less likely, but not unlikely so should not be ruled out.

Couple things:

a) check for packet loss...that'll cripple a TCP connection. Try pinging router or something else on the network that is pingable.

'sudo ping -A <router_ip> -c 10000'

b) does 'dmesg' say anything on your Linux box?

If I helped out pls give me a +

XBMC1:
i3-540, GT430, Ubuntu 12.04 min + Frodo
-> HT: 58" plasma, Denon 3808CI, Paradigm Studio 60, CC-590, ADP-470, Seismic 12
XBMC2: Atom330, GT240, Ubuntu 12.04 min + Frodo
-> Main: 50" plasma, Rotel RX-1052, B&W 683
Server: 20TB FreeBSD + ZFS

2% packet loss is not good.

Try moving things around for that connection. Try different network cables, try switching the cables to different router ports, etc. See if you can narrow down if it's a bad piece of equipment in the path.

+1 to Scottes

Your 2% packet loss sounds like a small number but it is definitely NOT doing you any favours..in the past I've seen it cause severe throughput degradation since it can mess up your TCP windowing and throughput due to retransmissions, etc.

http://en.wikipedia.org/wiki/Packet_loss...acket_loss

I don't see anything obvious in dmesg.

For testing drives speed on Linux, hdparm is one option.

Linux: http://sourceforge.net/projects/hdparm/ (Again, check with your package manager first as this is also very popular)

How-to: http://www.cyberciti.biz/tips/how-fast-i...-disk.html

I would test all drives.

It could be the controller, or even the file system used. It is less likely, but not unlikely so should not be ruled out.

iperf is FREE for all platforms.

Your UDP tests are showing losses too...I'd focus on your network troubleshooting. If no bum cables or switches,etc also look for Duplex mismatch...some machine full-duplex,other half-duplex,etc.

Heck no. As said by thirdnut, iperf is free - I had no though that someone would charge for it. And as you found, it is available for free.

Some cheekAngry Thankfully they set the price so ridiculously high (hopefully) nobody will ever fall for it.
Bad results for iperf - you definitely have a network problem...

Well it say's here in the link that was posted here earlyer it's 199$ http://www.iperfwindows.com/order.htm
and no download link there, atleast that I saw.
But enough of that.

I took the XBMC caple from the switch and plugged it into my router, so far i've received no packet losses and was able to download a
video with out a hassle.

Pinging router
Code:
--- 192.168.1.254 ping statistics ---

Thank you all for the help Big Grin
could it be that the port on the switch is broken?
And how do I know if the router has a gigabyte port?

Often an orange link light will indicate gig, but the router may show a green link light for gig. If I saw orange I'd bet on gig, but if I saw green it still might be gig. Google the model number for specs or manual, but it's best to see what the connected system says it's getting. Something like ethtool will tell you the speed the port is at. Better this way since a wonky cable can make a gig connection fail and drop it lower, so try different cables and ports.
