Bad performance with Nautilus and CIFS shares

Hi,

I have problem when copying stuff from my notebook to a CIFS share in my LAN: I get ~1,4mb/s but only with nautilus. The share is a NAS box which is not the fastest but when I copy stuff with Grsync I get ~6,5mb/s which is ok for the box. The NAS is connected to my home router (WRT54GL) and the notebook also, 100mbit wired on both sides. I am mounting the share via /etc/fstab which looks as follows:

//192.168.1.254/music /media/nsa220-music cifs credentials=/path/to/credentials,iocharset=utf8,uid=1000,gid=1000 0 0

Any ideas whats wrong?

Re: Bad performance with Nautilus and CIFS shares

I've seen this happen before as well with no explanation for the event.  I have a giglan setup; sometimes xfers are 60+ MB/s and other times 9 MB/s.

Oh 9mb/s would be great.:lol:
It's even worse when I use WLAN on the notebook.:rolleyes:

You'll never get alot of performance using wireless. Do the math:

802.11g: 54 Mbit/s = 6,75 Mbyte/s
802.11n: 108 Mbit/s = 13,5 Mbyte/s

Consider that these are optimal numbers, like when sitting right next to your router. IMO, Ethernet still rules performance wise and it't also more reliable.

That said, I'm also having CIFS performance problems when mounting shares. I get ~20 Mbyte/s on a gigabit network using Arch. Interestingly, I get ~60 Mbyte/s on Windows from the same server.

You're right, but I'm talking about ~1mb/s when using WLAN and nautilus....:-(
But it seems like I am not the only one, so what can we do, open a bug report?
