Question: iMac Pro + NAS + 10GBe ... Full Speed Finally
This may have been covered already, but I've spent the morning figuring out how to get full speed over 10GB ethernet.
- Turn off all file services except for SMB (ie - no AFP).
- Make sure MTU is same as iMac Pro and ethernet switch (if using one). MTU doesn't need to be 9000 ... 1500 is fine as long as all devices in the chain are also set to 1500.
On iMac Pro:
- turn off SMB packet signing. Other tutorials I've found on internet haven't worked for me ... official Apple instructions worked great.
Just a friendly public service announcement ;-)
