ReadyNAS RN524X00 has slow write speeds on macOS and Windows 10

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.

 

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

    You should post about this over in the ReadyNAS forums.


    Good Luck.

      How slow is "slow"?  Can you post some speeds from a NAS testing program such as http://www.808.dk/?code-csharp-nas-performance?  Sorry, I don't know a Mac equivalent.

       

      Have you verified on the Network settings of the NAS that the connection is at GBit speed?  A bad cable can make it negotiate a slower speed.

       

      Jumbo frames could increase your throughput, but enabling them can have the opposite effect if some of the machines on the network don't support them.

        Giving us the NasTester results on the Win10 system would be helpful.

         

        You should also try setting "Enhance MacOS" in system->settings->smb.

         

        Also I suggest disabling strict sync in the share settings and see if that makes a difference.

      OK, I'll try posting there if I can't get a good resolution here. Thanks for the suggestion.
