ReadyNAS RN524X00 is slow copying files

Question

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 10 laptop connected to the switch. All 3 have static IP addresses.

When I copy large files through my in-home network, not externally, from say my MacBook Pro to the NAS, the copying is slow. Same thing from the Windows 10 laptop to the NAS. Very slow. Even though I have Gigabit ethernet.

I have disabled IPV6 from a suggestion on another forum, but the copying still seems slow. I have also verified that it is not the cabling, since the NAS reports 1 GB ethernet.

Are there some settings on the ReadyNAS (or MacBook or Windows 10 laptop) to speed things up when I copy large files?

strict sync (a share setting) can slow down the write speed.

Can you try NAStester on the Windows laptop and share the speed?&nbsp;http://www.808.dk/?code-csharp-nas-performance

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).&nbsp; What was the fastest iteration?
&nbsp;
What model switch are you using?
&nbsp;
Not sure what you mean by "turned off wireless to avoid interference" since you weren't using it.&nbsp; Do you mean in the PC???

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

In Windows 10, I went to Network &amp; 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.&nbsp;OldTimerGuy&nbsp;wrote:&nbsp;&nbsp;How can I turn off strict sync to see if it writes faster?

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. &nbsp;Any other ideas you can think of? I really appreciate all the suggestions you have given so far. :-)&nbsp;&nbsp;&nbsp;&nbsp;

If the Speed not Crossing more than 12MB/s , There is definitely a 10/100 Mbps Connection in the network flow which is restriting the speed .
How about connecting direct Computer to NAS and try a copy by assigning a Static IP or try with another PC / MAC with 1Gbps Port ?
