I recently upgraded to Unraid 6.7.0, and I'm suddenly seeing poor throughput when downloading files from the server through SMB from a Macbook Pro running Windows 10 and connected through 5 GHz WiFi. I usually get around 300-500 Mb/s, but on 6.7.0, it peaks at around 6 Mb/s. Connecting via Ethernet doesn't have this issue. Uploading files to the server through SMB doesn't have this issue. Downloading files via SFTP doesn't have this issue, either. Oddly enough, it works fine when booted into macOS and connecting through SMB.
Rolling back to 6.6.7 restores the fast SMB throughput I was seeing before the upgrade. Any idea why this is happening?
