Hi Forum,
Until yesterday I used a simple chroot Debian installation (found at dns323.kood.org) with 2 x 500 GB hdd with no RAID. I wanted to replace one of the drives with a 1 TB drive. However I wasn't careful enough and suddenly became just another victim of the infamous 'wrong drive formatted' bug - which I have to say it exists even in firmware 1.08.
After this, I realized I'd never want to see this dumb, harmful, careless and dangerous firmware on my nas again, so I decided to go native. (I still wonder how the engineers at D-Link could manage to keep this bug present - it is really hurting)
I am using the dns-323 to share files in the home network via samba, run transmission-daemon (compiled from source) and do regular nightly backups via rdiff-backup and sshfs from other locations.
I was following the excellent tutorial of Martin Michlmayr and read a lot about the topic here in the forum as well. Everything seems to work okay (installation went fine, and with the new kernel the LED blinking issues are gone and fan control works flawless. I chose to install to an USB stick because it can be easily backed up and replaced if needed.
However I found that performance might be somewhat weaker than I got used to, especially samba performance. I don't know whether this is related to the different samba environment or because of the OS sits on a usb stick, I wonder how you configured your system.
For example while I'm writing this I'm copying a folder with some mid size files (1-10 MB each) into one of the smb shares and iowait is >40% despite of that I'm copying over wireless network and transfer speeds hardly get over 1.5 MB/s <- I didn't have the chance yet to test cable speeds.
I'm a little concerned about USB performance as well. Have you thought about putting some parts of the filesystem to tmpfs? This nas is clearly not loaded with that much ram, but it might worth checking?
Any performance related thoughts are welcome, thanks.

bad idea. every byte ram is sacred.

My performance is ok. i achieve 10 mb/s write and 14 mb/s read speed. not much worse than the stock firmware.

Eventually I was thinking about how little is 64MB and I have to agree so tmpfs should be skipped. I'm just curious what other techniques exist to avoid too much writes on usb.
* I mount my / with noatime,nodiratime options
* I tried to minimize logging bloat of many services (unfortunately logging to a remote host is not an option ATM)

Can you post a sample (and sanitized) smb.conf file? Still couldn't test throughput on my install, but my instance generally feels a bit more laggy (browsing shares, switching dirs) than I got used to.
Here's my current smb.conf (I'm experimenting with options)
[global]
workgroup = MYWORKGROUP
server string = %h server
interfaces = 127.0.0.0/8, eth0
bind interfaces only = Yes
obey pam restrictions = Yes
passdb backend = tdbsam
pam password change = Yes
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
unix password sync = Yes
log file = /var/log/samba/log.%m
max log size = 50
max xmit = 16384
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_RCVBUF=8192 SO_SNDBUF=8192
load printers = No
show add printer wizard = No
dns proxy = No
panic action = /usr/share/samba/panic-action %d
use sendfile = Yes
[print$]
comment = Printer Drivers
path = /var/lib/samba/printers
[MyShare]
comment = This is my share
path = /path/to/share
valid users = @mypeople
force group = mypeople
read only = No
create mask = 0660
force create mode = 0660
directory mask = 0770
force directory mode = 0770This is run via the stock lenny samba package. Shared partition has ext3 with default options.
