SMB on Synology NAS super slow AFP works fine

OS : Sierra
System : Macbook Pro 17" Early 2011
Connection : Gigabit ethernet

I have seen so may threads on this but no definitive answer or solution.

When I connect to my synology NAS I get a download speed of 14MB/s using SMB (server is set to allow SMB3 with a minimum of SMB2 large MTU). However, when I use afp I get the full 60-90MB/s .

Considering Apple say SMB is supposed to be the default now this is pretty strange. Does anyone know of a fix? Did Apple fix this in High Sierra?

Always seems to be like that on Synology. QNAP boxes are the other way, fast SMB slow AFP performance.

Just tested on my Synology: copied down a 23GB file at 60MB/s over SMB. The settings on my Synology were min: SMB1, max: SMB2. But I bumped those to min: SMB2 with large MTU, max: SMB3. Transfer rate stayed the same.

Only things I can recommend are... make sure you're up to date, and try changing your min to SMB2 (without large MTU) or SMB1.

Apple changed default signing of SMB to off in a High Sierra update, I think 10.13.4

Yes, High Sierra has the proper SMB signing which should fix this. Also see https://support.apple.com/en-us/HT208209
