Mac Pro dual ethernet port utilization

[Davy.Shalom]

Is it possible to somehow use both ethernet ports on the mac together for faster internet browsing?

Is your internet so slow that one cable won't cut it for you?

Your internet connection will be slower than a gigabit ethernet connection.

If your switch is gigabit and supports 802.3ad link aggregation, go for it.

From network preferences, follow the photo...
