Slow transfers to Goflex from Ubuntu Computer

[wment]

I have a ethernet GoFlex 1T on my home network with a Ubuntu 14.04 computer and a Win7 computer. The Win7 computer will D/L a 1gb movie file in about 60 seconds while the Ubuntu computer takes about 5 mins. All are 1 gigabit links. I have switched cables and switched ports on the router. This is also the case for the 1T USB drive I have on the USB port on the router. Any suggestions besides going to Win7?? Ubuntu has Apps that Win7 does not have.

Do you have similar hard drives and similar CPUs on the two computers? Usually the hard drive write speed is the limiting factor.

Thanks for the reply. The hard drives are similar. The Ubuntu computer is a 4core and the Win7 is a 6core. I would expect some difference but 5 times makes me think something is wrong.

What if you copy to /dev/null on Ubuntu? That would eliminate the disk speed.

I assume the USB and network devices show up as windows file system (NTFS). Since NTFS isn't REALLY a native Linux file system, the NTFS I/O support on Ubuntu may not be as efficient.

Have you ever done a wireshark capture and compared the results between the two?

More info:
I did an FTP transfer from the Goflex and the transfer took about 50 secs. The copy/paste function seems to be the problem. I downloaded a LiveCD of Ubuntu 14.10 and ran it from the CD and got the 5 min transfer. Running Speedtest gives me results like the Win7 computer. The lights on the router show all connections are at 1gb. (The Goflex is a ethernet NAS not a USB drive.)

OK, my mistake on the NAS vs USB ... How are you mounting the GoFlex on the Linux machine? NFS mount? What mount options?

More info:
From "Home Folder" I select "Browse Network" then select the Goflex. It returns a screen where I enter the login info before I see the file structure on the Goflex.

The slow transfers are the same for the Goflex or the USB drive hanging on the router.

It looks like the GoFlex doesn't do NFS by default. So you are running CIFS (windows network file system) on Ubuntu. You should look through the threads on slow CIFS performance on Ubuntu. Some of them may improve your performance. I don't use CIFS on my Linux boxes so I have no first hand help.

 

[wment]

ok, thanks

Is there a better way to transfer files besided FTP?

 

[kanewolf]

CIFS is the best choice for Windows. NFS is the best choice for Linux. Ideally a NAS that supports both protocols for every folder would be best. I see some threads online about adding NFS to the GoFlex. It seems possible, maybe just not easy.
