C3200 Tweak #2: Improving Samba performance

The preinstalled Samba server on both Cacko and standard Sharp ROM proves to be notoriously slow. This is mostly due to the strict syncing that’s enforced in the smb.conf - probably to avoid data loss. IMHO, it’s rather safe to disable this behavior and in turn get a nice speed bump. Here is how to do that:
On Cacko first delete the default link to the ROM copy of smb.conf:

sudo rm /etc/samba/smb.conf

Now, copy over from ROM and modify the copy:

sudo cp /usr/lib.rom/samba/smb.conf /etc/samba/smb.conf
sudo mcedit /etc/samba/smb.conf

Comment out lines

strict sync = yes
sync always = yes

Change the socket options line to

socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_RCVBUF=131072 SO_SNDBUF=131072

Please remember to reconnect the mounted samba share on your desktop system.
In my case the transfer rate on my Buffalo 10Base-T CF-Card jumped from 350 KB/s to over 820 KB/s.
