- Feb 15, 2007Thanks Marcel,
I used NTFS as file system. Backup my data to other machine and format my HD with NSLU2 with ext3, overclock the slug, then redo the dd test, now I have 7.7MB/s

Probably this is the problem!
1) What kind of filesystem do you use
2) Is this filesystem mounted "async"
- Using the sync option gives very bad performance
3) Is the disk directly connected to the slug and correctly
setup as high speed device.
- A usb 1 hub could cause this kind of speed.
4) Does the disk contains errors.
- Repeated reads/writes on error could also cause
serious performance losse.
Check what the output of the commands "mount" and "dmesg".

This is probably if you connect the cable direct to the slug.
I don't think that a wireless 54 Mbit connection has this
