ReadyNAS RN524X00 is slow copying files
I have my NAS connected to wired Gigabit ethernet. I have the NAS connected to my Orbi router via a switch, and using a Cat 6 patch cord. I also have my MacBook Pro (running Mojave) and an HP Windows...
strict sync (a share setting) can slow down the write speed.
Can you try NAStester on the Windows laptop and share the speed? http://www.808.dk/?code-csharp-nas-performance

How can I turn off strict sync to see if it writes faster? What does that do?
The average of 5 iterations on the NAS tester was 11.57 MB / sec (write) and 10.55 MB / sec (read). I don't know how that compares to other wired ethernet setups like mine, with 1 GB ethernet using cat 6. I have wireless turned off to avoid interference. The speed just seems slow, but maybe my expectations are high.

It is quite slow for end-to-end gigabit ethernet (should be ~100 MB/sec). What was the fastest iteration?
What model switch are you using?
Not sure what you mean by "turned off wireless to avoid interference" since you weren't using it. Do you mean in the PC???

Go to the shares page in the web ui, and click on the share settings wheel. Pick Settings from the context menu. Then select the network access tab, and click on "advanced". You'll see strict sync (along with some other stuff).
When it's enabled, the NAS waits for the disk i/o to complete on each write (basically turning off the write cache). So it will slow down write quite a bit - but not reads.

What model switch are you using? ==> I don't know what you mean by "model switch". Please explain.
Not sure what you mean by "turned off wireless to avoid interference" since you weren't using it. Do you mean in the PC??? ==> Yes. In Windows 10, I went to Network & Internet Settings | Change adapter options | Wi-fi and I changed it to "Disabled". I wanted to make sure wi-fi was not interfering with the 1 GB wired network I have in my house. Wi-fi connections are much slower than wired, in my experience.

When it's enabled, the NAS waits for the disk i/o to complete on each write (basically turning off the write cache). So it will slow down write quite a bit - but not reads.==> my read and write speeds are about the same: around 10 or 11 MB / sec. Since you said the speed should be around 100 MB / sec, I'm only getting a tenth of the speed I should be getting, both read and write.
Any other ideas you can think of? I really appreciate all the suggestions you have given so far. :-)
