I've tried to see if there were any difference between hardware of my NAS and the Flip's one. I've seen that Flip got a thermal cooler on his NAS CPU. There is nothing on mine (see attached pictures). I will try to see if the unit CPU is really hot during transfer. That could explain, for a same firmware, the hugh performance 

difference that we've got.

Hi,

not really guess it would be really usefull
to start all daemons that support it by the inetd

Triggerd by the recent discussion about ftp performance I check by box and
found out that the SMB transfer rate are only half of the once from ftp.

I get nearly 7 MB/s from FTP but only around 3.5 MB/s using SMB.

you are lucky having such values!!
i'm getting 1.4MB/s with SMB and 2.8 with CIFS
i've also done some testing and compiled another smbd in gentoo chroot on NAS with same performance results! so now I think the performance will not be much better via smb/cifs protocol on this NAS hardware. 

at least this cpu has ~70 bogomips compared to ~4000 with my 2.0GHz Pentium-M
when downloading from NAS, arm cpu in NAS is very busy for smbd (95% or more) and when downloading from my laptop to another computer it is around 2% (at laptop). 
so now i guess the performance of SMB is limited with NAS hardware.
has anyone got better results than yours 3.5MB/s ?
