FTP transfert rate 8.5MB/s smb/cifs is 1.7 MB/s

hi,

I have configure my dns with 2 HDD 500Go on RAID1. The Firmware is 1.0.5

With the firmware 1.03 i had the same transfer rate arround 9~10MB/s

Why i have this difference transfer rate on FTP and smb/cifs protocol??

My mount command is

smbmount //nas/volume_1 /mnt/data/nas/ -o user=hebus,password=xxxx

I obtain this rate with

dd if=/dev/zero of=/mnt/data/nas/LaBierreDuBoisQuiPousse/1go bs=1024 count=1000000

thanks

On fw 1.05 I can do >19MB/sec writes and >24MB/sec reads - so it's not likely to be the NAS - what do you have at the other end of this speed test?

Do your run an on-demand anti-virus software or a firewall on you Acer?  That will WAY slow down the transefer.  I get consistantly 17-19 MB/s writes with Gbit and no jumbo frames.

hebus - search this forum for NAS tester - it is a little Windows utility that was put together by a forum member that to test the read & write speeds.

When I asked what was at the other end of the test, I wasn't really looking for a brand name - but rather the OS, I suspect you're unix some linux or unix distro and I believe some of them have had results like you describe due to issues wuth SAMBA.

Re: FTP transfert rate 8.5MB/s smb/cifs is 1.7 MB/s

hi,

I have run Nas tester from Vista and the result is arround to 15Mb/s (on Gigabit no jumbo frame RAID1) so the NAS seem not  to be involved.

However i don't understand this. I have a lot of Samba serveur in my work and i have never seen this difference between Windows ans Linux.
I think it's a mount (smbmount) option that require for work as well as Windows OS, but when i use an option of this command i think that the NAS ignore it.

I continue to search
thanks

Essentially what you have done is established that whatever problem exists, it exists at the Ubuntu end - and so that is where you need to look - there are other discussions of this nature, not necessarily with Ubuntu, try searching the forum for more dteails.
