I'm trying to migrate data from a Synology 416play through a mapped SMB share from Unraid on the Synology. The file transfer starts out great and I'm able to hit more than a gigabit out but shortly after speeds tank and start bouncing around between 50mbit/sec to 200mbit/sec, and this is regardless of the size of files being transferred. As an aside I've also had issues with really slow SMB share speeds to a mac, but from a few searches I see that might be an issue I haven't even begun to dive into that yet.
I know I'm asking a lot, but is there something simple I'm overlooking? Everything is up to date, everything is connected through a 2.5gbps switch with 5gbit bonded on Unraid and 2gbit bonded on the Synology, and Synology shares to my Mac are nice and fast so I don't think the issue is there. Thanks so much!
