974 Can I get increased performance from Link Aggregation in macOS?Dec-22-19
We have found that a macOS client just ping-pongs back and forth between the two ports with no increase in performance. There is an increase in performance with only a macOS server that is connected to multiple clients. To get link aggregation to work, the switch must be capable of supporting it and the two switch ports connected to the Twin 10G must be configured as bonded ports.

1065 I'm getting very slow performance with my Presto 10G PCIe card or Twin10G Thunderbolt 10G adapter with OS X 10.11-10.12.Dec-22-19
In macOS 10.11 and 10.12, SMB signing is turned on by default. This is no problem for gigabit ethernet, but SMB Signing severely limits the performance of 10 gigabit ethernet. Apple has published a tech note how to turn off SMB signing: "Turn off packet signing for SMB 2 and SMB 3 connections". This note requires the use of the terminal application and a number of terminal commands, so some familiarity with those tools is required.

In macOS 10.13.6+, Apple has turned off SMB signing by default.
