screenshot I'm suffering from poor network performance on my PI.

I use samba to copy files from W7 to an external 3,5inch usb3 drive, NTFS formatted and mounted on the pi using NTFS (not the 3g).

I have seen a lot of reports of slow networking with samba but not many fixes.

After upgrading my firmware the speed dropped from 3.xx MB/s to 2.7x MB/s

CIFS is a slower protocol to start with, and 27/30Mbps isn't terrible. The usual fix is to change over to something like NFS or rsync (or even SFTP/SCP). Overclocking might help if it's safe for you to do so.

  • Is it normal to have only 30mbps over a LAN network? I did notice a small improvement with a small overclock so I guess it's very CPU intensive...

  • Yeah, that would make sense that overclocking would improve the rate. NFS (without Kerberos) doesn't have much overhead to it as it's a really simple protocol without encryption. CIFS is more complex and SFTP/SCP uses the encryption in SSH to transfer files, but you can sometimes use a faster and less secure encryption method to boost performance. 30mbps on a 100mbps LAN isn't great, but it's not terrible either.

  • I now use the pre set 'turbo' OC mode (1GHz) That seems to pull up the transfer speeds to an acceptable level.

From my knowledge all the PI uses USB 2.0 technology which means that you are limited by the tech here. i believe that USB 2.0 cab achieve speed around 5MB/s. So be glad that you are able to pull out the transfer speed you are getting.

I have A PINAS as well but get speed in the KB/s when transferring data to the PI
