Read and write to Readynas duo v1 under windows very slow

I migrated to windows 10 and for a while wondered why my videos were playing very slowly. Then started to look for Windows 10 improvements and have reinstalled network drivers etc.

 

I connect to a 100mbit router (the internet gateway) on to a gigabit switch on which the Readynas is placed

 

i tried NAS performance tester

    I'd like to clarify.  You have a PC connected via 100mb/s ethernet, and the NAS and a file server are connected via gigabit.

     

    When you copy a file from the NAS to the server through the PC, you get 12 MB/s.  Is that right?

     

    And NAStester shows ~5 MB/s between that NAS and that same PC.

     

    Is that correct?

      Sorry for being bad on the description

       

      My windows 10 desktop PC connects directly by 100mbit LAN to a Router, delivered by the internet provider

      The router is connected to a Gigabit switch containing a number of units

      On the gigabit switch I have the readynas Duo and a server I use for multimedia display

       

      If I copy to the NAS from the desktop PC I get something like the report, but in general the transfer speed reported from total commander or windows is around 150-200 kbyte/s or less

       

      If I copy from/to the multimedia server from the desktop PC I get 10-11 MB/s consistently

        Can you do a test between the multimedia server and the duo?
