What happens if you try doing the same thing, but mounting it via smbfs? We had a similar problem a few months back restoring a 650MB backup from a SMB-speaking NAS. Firstly, we tried it on FC6. ----------------------- $ time cp foo.tgz /tmp real 12m18.892s user 0m0.014s sys 0m1.581s (After which we killed the process to put it out of its misery.) -rwxr-Sr-t 1 xxx yyy 62763008 Dec 4 12:22 foo.tgz - 62 MB transferred in 12 minutes over a switched full-duplex Fast Ethernet link - inside the same rack. ----------------------- Unmount it, remount the same NAS share with 'mount -t smbfs': $ time cp foo.tgz /tmp real 3m42.517s user 0m0.160s sys 0m13.955s -rwxr-xr-x 1 xxx yyy 654138296 Dec 4 12:27 foo.tgz - the whole 654 MB transferred in under 4 minutes. The only difference between the two tests was 'mount -t cifs' versus 'mount -t smbfs'. ----------------------- We did the same with SuSE (10.0 or 10.1, IIRC) and got much the same results. I don't know where the problem is, and don't have time to isolate the cause; but personally, I'm avoiding cifs until it compares to smbfs. cheers, Gideon.
