Depending on your setup, using NIC teaming aka 802.3ad may not provide any benefits to you.

The maximum that a single network connection can transfer is whatever a single link can do. You won't be able to do a Samba transfer of a file that goes at greater than 1 Gigabit for example.

This limitation is due to how 802.3ad was designed and the load balancing algorithm that is used. It will force all packets from a single connection down 1 link to prevent issues with out of order packets. It won't spread them out between all the links you've got.

The algorithm uses the MAC address and source + destination IP addresses to calculate a hash value which determines which link to use. There are nonstandard implementations which also include the port numbers in the hash calculation.
