I've just managed to access my windows share from Ubuntu but am now getting write speeds (to xp share) of only 9MB/s over my wired network, anyone have any ideas as to why this may be? I've googled but can find no specific answer.
My NIC is:
Ethernet controller: Broadcom Corporation NetLink BCM5784M Gigabit Ethernet PCIe (rev 10)
(from lspci) on a Dell studio 1737)
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.
My wireless network is giving me a fit. Slow transfer speeds and then I lose connection and have to reboot.

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 have read many threads but cannot find a solution on this code...
Now no matter how i transfer if its from HDD to HDD or to SSD i never get more then 18-20MB/sec, i just tried booting to my live CD and was able to transfer with 24-25MB/sec
This is really slow, since the worst (2.0TB) can do a minimum of 30 READ
Anybody got any ideas, this seems to be something that has plagued ubuntu for years, and no i don't want to try other distros, i tried almost all of them a year ago and finally went with ubuntu
I'm at the end of my rope here. And the most frustrating part is, I've found many posts all over the web from others who have had similar problems, but they ALL seem to be older distros and those solutions don't work for me. "Find Similar Threads" only yields one thread, and I don't have the file mentioned in the answer (the original poster didn't either).
Computer: AMD 64 Quad core, USB 2.0 on front bus, dual booting Vista and Ubuntu 10.10
Device: New Sansa Clip+ 8GB mp3 player
Problem: When I transfer files to my mp3 player in Ubuntu, I max out at about 150 KiBbps. It's painfully slow - it takes me half an hour to transfer 300 MB worth of albums. I had similar problems with an older player that may have been usb 1.1, but this one is brand new. And when I switched to Vista (first time in months, thankfully), I was able to transfer the same files at upwards of 3 MBps. I know that flash devices often can't write anywhere near the max speed of USB 2.0, but obviously it can do a whole lot better then 150 KiBps!So, same hardware, same files, different OS - the problem must be with my Ubuntu config.
I tried using my USB to transfer a 500MB file, the speed came up as 1-130 kb/s. That is pathetic. I should be getting more 25MB/s.
View 14 Replies View RelatedI have a Hitachi SimpleNET adapter (entry-level NAS device) on a Seagate FreeAgent 1TB external HDD (formatted ext3). The NAS device is connected over 100MB/s ethernet to a Netgear Wireless G router. All other devices connect using Wireless G. The NAS runs embedded Linux on an ARM processor and it runs vsftpd and Samba for file transfers.
If I transfer a large file using an FTP client the transfer maxes out at around 2.5MB/s. For my purposes that's good enough, especially considering the Wireless G bottleneck. If I transfer a file from a Windows 7 client (using samba) I get around 2.2MB/s. I know the CIFS protocol has more overhead than FTP and the difference in speed isn't that noticeable.Any combination of Ubuntu and Samba results in me getting less than 1MB/s. I've tried mounting it through Nautilus (GVFS) and /etc/fstab. FTP from this same Ubuntu client gets around 2.5MB/s.
I don't have root access on the SimpleNET to change the smb.conf. I've made a few adjustments to the mount options with no success. how to either speed up 10.04 as a Samba client or mount a folder on an FTP server locally? I've tried both curlftpfs and FUSEFTP. With curlftpfs any write operation results in an I/O error and it crashes intermittently. With FUSEFTP I never got that far and couldn't even browse the folder.
I'm finding that the internet speed in Ubuntu 10.04 is over twice as slow as the speeds that I am getting in Windows 7.I've tried disabling IPv6 through Grub and Firefox but it didn't really help much.. anything else I can try?Connecting through wireless at 54 Mbps.
View 2 Replies View RelatedI'm using a Netgear WN11v2 wireless USB card, which I've read some people can't even get working with the default Ubuntu wireless driver. It works for me, but it disconnects fairly often, and download speeds are extremely slow, like 12-15 kB/s. I have broadband, and am running Ubuntu 11.04.
View 3 Replies View RelatedI am currently staying on a university campus in Taiwan. Internet on Ubuntu Lucid 64bit here is often painfully slow, except for connections to Taiwanese websites. I dual boot with Windows 7, and there is no problem there. For instance, I downloaded the same piece of software (Spideroak) on both Win and Ubuntu, with Ubuntu I had to try repeatedly as the download would not complete, and in the end it took several hours to download. On W7, it took 10 minutes. What is Windows and Ubuntu doing differently?
I tried disabling ipv6 for this session by running sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1, as a number of posts mention improving connection speed that way, but no effect.
I know that websites from Taiwan are working well, because I am getting my Ubuntu updates from a Taiwanese mirror: updates are fast, except for packages in the 'partner' repos (presumably not loaded from the mirror) which take hours to load, if at all. I don't want to depend on Windows for large downloads... (I don't want to depend on Windows for anything).
I'm on Ubuntu 10.04 and I'm having problems with internet speeds on wifi. I have tried the two available networks on my university campus and both of them are very slow with 10.04. I'm not having problems with Windows 7 running on these networks. Although, the wired network works perfectly fine, with normal speeds. I've looked around for help but I could not find anything specific to this problem.
View 2 Replies View RelatedI've been using Ubuntu for a while (though I would not consider myself an "expert") and have just gone back to school. I live on campus and connect to the network through an ethernet cord. On Windows, the download speed is 1 Mb/s by default, but if you go through and configure the network card (turning off the auto-negotiation and setting the speed to 10, duplex full) the download speed will increase to 10 Mb/s, a considerable difference. So, I tried to do this in Ubuntu by opening the terminal and typing the following:
sudo ethtool -s eth0 autoneg off speed 10 duplex full and all of a sudden, my computer isn't connecting to the internet. When I type: sudo ethtool -s eth0 autoneg on it suddenly starts working again.
Trying to watch movies between my systems and I'm getting upload speeds of 6.5 kb/s from my system to the one connected to the tv. I'm running Ubuntu on both machines, tried with VLC and XBMC. Both are running wirelessly but I know that this issue is new, I used to get at least a meg a second on LAN.
View 9 Replies View Related I just bought a 1Tb hdd and reformatted to FAT32 it is connected via eSATA to SATA cable.At first I transfered music that initially was getting speeds over 100mb/s (according to nautilus) after about a minute it started to dwindle. Now most files will range somewhere between 8-20mb/s although I've only seen a couple go beyond.i edited hdparm.conf to enable DMAHere is the output of hdparm -Tt for both internal(sda) and external(sdb) hardrives.
Code:
/dev/sda:
Timing cached reads: 14872 MB in 2.00 seconds = 7444.68 MB/sec
Timing buffered disk reads: 372 MB in 3.00 seconds = 123.91 MB/sec[code]....
What is the issue this output leads me to believe that I should be getting the same speed I once got.I'm running Intel Core 2 duo at 3.00, ASUS P5Q (enabled AHCI) and 4gb ram 12gb linux swap. Also Karmic 9.10
I have been transferring files over the network. But I am sure It should be HEAPS faster than 8MB/sec
View 5 Replies View RelatedI'm experiencing slow speed transfer between two wireless connected laptops running ubuntu 9.10. Using SSH to tranfer files between these two laptops, which connect to the internet via a wirelesss router, with good speed. This is why I'm surprised by this low speed : 52.3 KB/s, averaging 3 hours and 31 minutes for a 700 Mb movie. Is there any way to make this faster ?

My doubt is will it improve the bandwidth of path? or I need connect different socket?
I have connected two computers with each other both having fc installed. Now, when I tried to transfer a file from one computer to another using scp command, sometimes the file transfers very slowly and sometimes very fast. I wana know that why it sometimes transfers slowly. By slow I mean much slower than a file downloaded from a dsl.
View 2 Replies View RelatedWe have a server and we have instales an Open suse 10.3 on it. We created a Samba server also. Made to share folder, that we acces from network from other computers that have xp.
The problem is if we try to copy from server it is very slow only 100-300kb/s. The strange thing is that if i copy 1 file then its slow but if i start to copy another one the speed gos up to 10-15mb/s. Evry time i want to copy somethin or install from that server i need to start another copy. If i copy from a comp to that server the speed is normal only if i copy from server its slow.
Ok, the only thing I remember doing is changing out my hard drive because it went bad. I swapped in a new one and reformatted with Windows 7. (I can hear the boos and hisses as I type) Anyway, now file transfers are exceedingly slow. They are ~10KB/s when they should be ~40MB/s. The odd thing is that it mostly occurs on large files, but not all large files and sometimes smaller files are affected. Copying files from one hard disc to another on the server, as well as copying from the server to Win7. Local files are not affected. The problem does not occur on my laptop which has Slackware Linux on it.
Another thing about the problem is that when I mount a disc image on a virtual drive, access time is very slow and windows explorer is very unresponsive and often locks up completely.
I have a samba server with Slackware Linux on it and a Windows 7 client. DHCP is configured through dnsmasq. (dhpc-host=<mac address>,<computer name>) Every now and again, dnsmasq seems to conk out when I try to access the network with my Win7 machine. I then have to reboot the server, as my only access to it is via SSH and I don't have a video card in it. After the server reboots everything is fine until accessing the network with my Win7 machine conks it out again.
I've tried different MTU settings, different network cards on the Win7 machine(Dlink and realtek), various regedit hacks, but none of them produce any results.
My main pc is this Fedora 10 pc. I have two other pcs that run different Linux distros from time to time. What is the basic setup to share and transfer files between the 2 or 3 pcs? They are connected through a 2wire modem/router.
Do I need Samba installed? or is that only if to need to network with a Windows pc?
this is all on LAN.Whenever I transfer files through the router A to a pc connected wirelessly, the internet hit the speed of molasses. What can I do to rememdy this? I was thinking about having my fedora box connect wirelessly to the internet, through router A, and then bridge via ethernet to router B and then have my pc always connected to router B, so when i transfer files, router A remains unaffected. Is this correct logic?
View 1 Replies View RelatedI am having a problem trying to transfer large file (~700MB) from one station in my home to another. I have 3 PCs hooked up through a router. 1 is wired to the router and the other two are wireless. One wireless is a laptop that has a built-in Atheros wireless card that was supported during the FC13 install. The other wireless has a plug-in wireless card made by Belkin (F7D1101). I had to use ndiswrapper to get it to work on FC13.(BTW all PCs are running FC13)
The one with the Belkin card is, I think, the problem. The one with the Atheros card will transfer files at a rate of about 8MB/sec to the one with the wired ethernet connection. The one with the Belkin card will not transfer at rates over 300KB/sec to either of the other two PCs. I have tried file transfers both encrypted and not and it makes no difference.
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.

Reading and writing works absolutely fine with small files but large files are tediously slow in writing to the server. (rw,no_subtree_check) are options in exported directories.
What is your experience with NFS and how can I speed up large file/folder transfer(write) speeds?
I've fixed almost everything except this problem. My network card worked fine on Windows but since I switched from Windows, file transfer over the network using my network card is horribly slow, 30kbps max on 100mbps wired connection. I know my network card is working fine, and I'm trying to copy files between my Ubuntu PC and windows PC, I've set up Samba as recommended by these forums, I can transfer files when using wireless connection, but I still can't transfer files at a speed faster than 30kbps on a wired connection.And the funny part is, it's fast when copying files from Ubuntu to Windows but it's slow the other way. And I've tried this with more than 4 different Windows computers.lspci returns this for the network controllerCode:Silicon Integrated Systems [SiS] 191 Gigabit Ethernet AdapterIs there any way of updating drivers or something that I can do to fix this problem

I am using Ubuntu 10.04 and my internet works fine except for my download speeds. In Windows, downloading the same file, it downloads at around 200kb/s but in Ubuntu, it hovers around 20kb/s and never tops 50kb/s. Any idea how I can fix this because I really don't want to go back to Windows but I may have to.
