Hardware :: Unbelievably Slow Transfer Rate To IRiver Media Player
Apr 7, 2010
I recently purchased an iRiver P7 media player which I am using with Rhythmbox under Ubuntu 9.04. The transfer speed when uploading files to the player is phenomenally slow - the first 50 or so MB reported virtually instantly then the speed immediately drops to about 12-15KB/sec yes KB/sec so a 3-400MB video file takes hours to transfer to the player. This happens with the internal memory and the added memory (SD card) too, althoufg it is faster ror the SD card. No other devices have ever behaved like this on this system (and I have used 2 different Creative players, a different iRiver player and numerous memory sticks). The computer is dual booting with windows (for once that was useful) and under windows it doesn't happen, the speed is as expected so it isn't the hardware. I don't want to have to resort to damned windoze just for this. dmesg after plugging in the player shows it identifying both the internal storage and the added SD card but I don't understand the rest of it:
[code]....
This last message gets repeated lots of times, and during transfers it seems to be issued continuously and I suppose this is why the system is so slow because it is always retrying loads of times before a success.
Iam using public ftp server,the server file transfer rate is very very slow & the server is also very slow,In which way can i check the server to make it fast,can any one give sugession on this.
I would like to know if it is normal to experience 10MB/s data transfer rates during copying between partitions on my local hard drives (Toshiba 250GB 5400rpm SATA) while having three times faster (30MB/s) transfer rates between local partitions and USB drives (Kingston 8GB).
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: gettons@gettons-desktop:~$ iperf -c MYSERVER ------------------------------------------------------------ Client connecting to MYSERVER, TCP port 5001
Same computer and flash. Two results on different OS:
Write speed under debian: 0.4 MB/s Write speed under Windows: 6.6 MB/s
From what i've been reading on the net I guess it's something to do with the mount - sync option. I've notice that there are couple of workarounds but all of them are pretty tedious.
Is there any simple (GUI - one/two clicks) tool that allow to mount/unmount flash disk easily using the correct options?
I'm using Squeeze 6.0.2 (Kernel 2.6.32-5-amd64), gnome 2.30.2
As most do now my local library has a decent catalog of audiobooks, which I would like to be able to listen to on my iPod. These books can be downloaded only by using Overdrive Media Console (which is available only for Windows and Mac, and also requires Windows Media Player to work!) and iTunes if you want to transfer to an iPod.
I've searched around for Linux friendly solutions. They fall into two categories, try Wine/virtual machine/dual boot to run the required software, or give up. But pretty much everything I have found is about four years old now. Has anything changed in the last few years, or is this still pretty much the way things are? At the moment I use my girlfriend's Vista computer to download books, but I would like to be as Windows free as possible, and able to do it on my own computer.
Can anyone offer advice for being able to download audiobooks and put them on an iPod, with a minimum of non-Linux software? Relatedly, I would also be quite happy to replace the iPod firmware with Rockbox, but from what I can tell that would make library audiobooks even less accessible (so asking if this is an option is like asking for $10 after being refused $1).
I installed Opera 11 a couple of days ago and it is incredibly slow. After entering a url it just sits there with "Document 0%" in the location bar for thirty seconds to a minute, then renders relatively fast. I've gone back to both version 9.xx and 10.63 and they are both faster.
My friend bought an old hard drive. He noticed something with the hard drive that it was just replaced with a SATA socket. So meaning, the SATA socket was soldered to the PATA hard disk to replace the PATA socket to SATA socket to make it a SATA.
Now the question is:
1. Does the Transfer Rate of the harddisk (that has been replaced from PATA socket to SATA socket) would be SATA transfer rate? OR would still be PATA transfer rate?
I started a thread in the hardware section, but I've narrowed it down to being a software issue. The problem is that all USB devices are written to at about 1MB/s, and is read at equally slow speeds. After testing my computer on an older Ubuntu release (8.04 32bit), I verified it wasn't a hardware issue, because the read and write speeds were like they were supposed to be. Then, I downloaded the 32bit release of the Ubuntu version I'm currently using (an up-to-date version of Natty) and booted the live cd of it. It was equally slow there as well.
The read/write speeds are equally poor on openSUSE and Arch Linux, so I don't think that it's an issue with Ubuntu, as much as it seems like a kernel issue (or maybe not, you guys can correct me if it seems like it isn't ).
I have a LaCie NAS which is mounted on my main linux machine over a wifi LAN using the cifs file system. I would stupidly expect the transfer rate between my hard drive and the NAS to be limited by the Wifi speed (54 Mbps) but when I transfer files, the speed tops at 1.9 Mb/s which is roughly 15.2 Mbps. The most puzzling thing is that when I do multiple simultaneous transfers, I reach approximately 3MB/s in total but none of the individual transfers goes beyond 1.8. Does anyone have an idea about what is keeping the transfer rate so low?
Sd card transfer rate is 133mb/s and ide transfer rate is same 133mb/s. Using no extra wire and direct connection, why is that sd card is much gradual than ide?
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.
I have a FC13 box that has both Gnome and KDE sessions installed.
I have noticed on the KDE session that data transfer rates are slower than when I use Gnome.
In Gnome, I can transfer files between my FC13 machine and my Ubuntu 10.04 pc at a rate of 6.5 MB/s (52 Mb/s if my maths is correct), but in KDE the rate is only 3.5 MB/s (28 Mb/s).
"ethtool eth0" shows my NIC speed as 100 Mb/s. Obviously I am not hitting anywhere near that speed in either session, (a separate article may be happen in the future to address that), but I am curious as to why KDE is that much slower for file transfer.
I have not tried this, and I am only wondering about the result.Let's say that I have a PC/Laptop with two network devices: an ethernet and a wireless. Can I connect both of the to the same network (if this network allows both connection) to increase the transfer rate between the PC/Laptop and the server???
I have 2 10.04 machines connected through a switch, both with gigabit on board ethernet. Both machines show 1000 Mb/s connections.When I transfer large files (gig plus up to multi-gig) the maximum I get according to ftp 11472 kB/s.I did rough computer school math in my head and that seems low but I'll admit I know very little about network transfer rates.My question is what transfer rates should I expect to get between the 2?
Whenever I transfer a movie into my 16GB USB flash disk, my whole system becomes windows-like and unusable!
When i drag the file(s) into the USB disk folder, it starts out fine and pretty darn fast (25mb/sec) then slowly decreases until it's unbearably slow (3m/sec) and as a side effect my whole system starts deteriorating. I basically have to wait for the file to finish transferring before i can use my desktop again!
This has been happening with every version since Karmic (all 64bit)- I put up with it because I don't use the USB stick that much.. but lately it's been my go to source for transfering large files to/from work.
I just bought a HP 3085dx laptop with an intel 5100 agn wireless card. The problem: copying a big file over the wireless to a gigabit hardwired to the router computer only gives an average 3.5MB/Second transfer rate. If I do the same copy from my wireless-n macbook pro to the same computer. I get a transfer rate of about 11MB/sec. Why the big difference? I noticed the HP always connects to the 2.4 GHZ band instead of the 5GHZ bands...
[jerry@bigbox ~]$ iwconfig wlan0 wlan0 IEEE 802.11abgn ESSID:"<censored>" Mode: Managed Frequency:2.412 GHz Access Point: 00:24:36:A7:27:A3 Bit Rate=0 kb/s Tx-Power=15 dBm Retry long limit: 7 RTS thr: off Fragment thr:off Power Management: off Link Quality=70/70 Signal level=-8 dBm Noise level=-87 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0
I am not getting any errors. I don't know why the bit rate is not known. My airport extreme base station typically reports that the 'rate' for the hp is typically 250~300MBi and about the same for the MacBook Pro. The hp is about 6 inchs away from the base station. Is there anyway to get the rascal to go mo'faster? Is there anyway to get the rascal to use the 5GHZ band.
Ubuntu10.10.i want a media player with all media codecs.it should able to play all formats of videos and audios so please suggest me a media player.(i used km player in windows i want a media player like that)
I checked task manager the other day and I discovered that on the network history monitor some bits and bites were transfered in a repeating pattern (like a beacon). The transfer rate (when active) is about 149b/s receiving. And about 70b/s sending. What is this?
No Internet-related program was running from my part...In an attempt to pinpoint what was causing this, I occidentally removed the tools located left and right on the time and date. I've rebooted since but still no tools. The 0/I button is also gone.
in software.opensuse.org site if we serch for a software the result will be like the following
vlc KDE:Unstablelayground/openSUSE_11.4_KDE_Distro_Factory This is the stripped version of the VLC media Player. VLC media player is a highly portable multimedia player for various audio and video

Crystal Player has one very good playback speed troubleshooting feature - it uses large buffer of decoded frames (about 50% of RAM). Is there any player with such features in ubuntu?
When playing coyright protected DVD's in Ubuntu 10.10: the following errors occur:Movie Player Error message:Error occured Could not read from resourceVLC media Player Error essage:Playback failure:DVDRead could not read block 0.Non copyright protected DVD's play fine
Iam using opensuse 11.1. I want to know which is the best player that can be used in suse, which should support all codecs. I have tried totem player, xine, kaffeine, Noautun etc. But none of them is good. I have tried to install vlc player, but it shows a lot of dependencies too..it was not successful.

Are there audio player for Linux, that can play audio with some coefficient, that I can manually change, something like x0.5, x0.7, x0.79, 1.0 - normal, x1.5 etc...
I've got an annoying problem with refresh rates in everything to do with videos. Basically, anything that requires a quicker refresh than using a word processor. This includes flash movies on a website to playing an offline video. In website flash, the video tends to, well flash on occasion. The other sort of thing is pan lines or whatever they're called in videos like a simple .avi movie.
I currently have the nVidia 270.29 drivers installed for my GTS450 card, but this was happening with older versions. My monitor is a Samsung SyncMaster 943 which is detected. The resolution and refresh rates are sort of fixed on auto configuration. What I mean is, is that I can use the drop down menu to change the resolution to a manual option, and then it allows me to select a refresh rate, but only limited to 60 and 75Hz.
This setting will stay as is until I need reboot or restart Ubuntu. Even clicking on Save to X Configuration File is not a keeper. However, here's another problem. Doesn't matter which refresh rate is selected, I still get the above problems. The same resolution and refresh rate yields no problem under Win7 which I've dual-booted with.
