Hello everyone,
I was wondering if there a not a whole bunch of features a router would need that I could/should disable to achieve maximum performance as a NAS.
For instance, OpenWRT creates 2 interfaces LAN and LAN6, but I only use IPv4, so would there be a benefit to deleting LAN6? Are there any routing or Firewall features running in the background without me having set them up?
Essentially it is one LAN port with static IPv4 and I am using SSH/SFTP as the only transfer protocol.
Any recommendations would be appreciated
Thank you
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
ubus call system board
cat /etc/config/network
cat /etc/config/dhcp
cat /etc/config/firewall

None of the topics you mentioned will have any detrimental effect on NAS performance. A firewall will only require CPU cycles, if packets are passing through it, if everything is on LAN, there is no filtering or routing going on and (almost) zero CPU cost (just a few KB used RAM, negligible). IPv6 is not a (potential) reason for performance issues either, your clients select which IP protocol they want to use - and they'll only use either of them.

That is a performance sink. The encryption costs far more than all other aspects of the data transfer. When I remember well the original firmware could do around 40MB/sec using samba, while using an ssh tunnel lowered the throughput to 1~2MB/sec, at a CPU load of 100%.
Try FTP instead. And if you can't, because of evil internet, try FTP in combination with wireguard. Wireguard is also encryption, but much cheaper than ssh.
