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!
If you go to the Network page, does it show you are connected at 1Gbps? Does you computer show a similar connection speed?
Also, download the log zip file from the NAS, and look at the packet statistics in network_settings.log. You can cut/paste them into a post here if you aren't sure what you are looking at.
Have you measured the speed for normal NAS access (not time machine)? If not, try copying a large file (perhaps 500 MB) in both directions, and let us know how fast that works.
BTW, is the NAS model in your first post correct? The RN3138 is a 4-bay rackmount model.
Here is the 2nd file.
