Transfer Speeds Cut in Half Between High Sierra & Synology NAS vs Windows 10

[legacybk]

Im trying to figure out why the transfer speeds between my computer and Synology DS1817+ has been cut in half since installing both Sierra or High Sierra.

I was previously running Windows 10 and the speeds i was getting was 110-135Mb/s. Transferring 1GB took about 10 seconds. But now that im on macOS high sierra, the fastest itll go is 55-60MB/s.

In System Information, my Gigabyte Z270X-UD5 Motherboard shows 2 different ethernet cards with a different Kext being used on each:

RealTek RTL8168E/8111E - RealTekRTL8111.kext
Intel 1219V2 - intelmausiEthernet.kext

Physically, I have one ethernet line for internet, and the other is directly to the NAS.

Have you tried both SMB and AFP?

Hi pastrychef,
Yes, the Nas is connected through SMB.

Did you try AFP? I use AFP with my Synology clone and i get over 110MB/s over 1GbE and up to 800MB/s reads and 300MB/s writes using AFP over 10GbE.

Try this:

1. From Finder, press Command+K.
2. In the "Server Address:" field, enter "afp://" followed by the IP address of your NAS. (example, "afp://10.0.0.2")
3. Also, make sure that AFP is enabled on your NAS.
