Very Slow Read/Write and Time Machine Backup
I know this has been written about for many of the ReadyNAS servers, but I haven't seen it for exactly the same issues I'm having.
It's slllllloooooowwwwww. Get the point. It will take weeks ...
I thought I'd close this discussion with the final outcome.
I did open a ticket with Netgear. They did replace the unit. But it was still dreadfully slow. It must be something in their OS that makes writes of small files dreadfully slow. I even tried it on a high end Windows PC. Same slow speeds.
And I did once again verify that I did not have these slow speeds with an old Buffalo NAS that I still had lying around. I got between 30-45 MB/second with that vs the 1 MB/second with the Netgear NAS.
So I ended up purchasing a 5-bay USB-C drive enclosure to connect to my Mac. Of course, I get blazing speeds with this.
For now, I've put some old 3TB drives into the RN3138 and I've relegated it to be a backup NAS for my small computers.
If/when they ever fix this issue, I might come back. But I don't expect that to ever happen.
VERY DISAPPOINTING!

I don't see where you turn volume encryption on or off.
It's off by default (and you'd certainly know if you were using it).

I'm running a plain vanilla system. The only services running are SMB, UPnP, HTTP and HTTPS. Currently, I even have antivirus turned off.
File search is also off.
No apps are installed.
SMB3 Transport Encryption has 3 options -- Enable, Desired and Required. Right now it is Enabled.
So it's not
- the load on the NAS (and even if it is encrypting the transport, it should be capable of faster speeds with small files).
- the disks since you switched over to ssd
- a volume issue, since the switch to ssd created a fresh volume
- cabling, since you replaced that (and aren't seeing issues with ethernet errors)
- your infrastructure, since direct connect gave the same performance
- the mac itelf, since you've tried more than one PC.
Looking once more at network_settings.log, you still have ipv6 enabled. That can create performance issues with Windows (especially when ipv6 isn't enabled in the router). I don't know if that's also an issue with Macs - but you probably should disable ipv6.
After that, I am out of ideas on things to try. So if that also makes no difference, then perhaps see if JohnCM_S or Hopchen are willing to analyze your full log zip (they might possibly see something there).
If you are conversant with linux, you could log in with ssh, and see if top (or one of the other linux tools) gives you any clues on where the performance bottleneck is.
I have turned off IPV6 and will try another copy. If I see it bogging down again, I will just abort it instead of running it the entire 3 hours has I have been.
I used to be very comfortable with Unix, but it's been many, many years. Without instructions, I doubt I could figure out top.
Will the other 2 gentlemen see this link because you added their names or do I need to contact them individually?

The @ should give them a notification. But it does no harm to send them a private message and ask for their help. Use the envelope icon on the upper right of the forum for that.
Copying without IP6 produced the same results.

I was afraid that would be the case. Then I am out of ideas.
Well thanks for trying. I did PM the other 2 gentlemen. If nothing soon, time to place a warranty claim I'm afraid.
