You always want full duplex. Full duplex means the interface can send and receive data at the same time. Half duplex means you will have collisions and slower network performance due to dropped packets, as systems back off and resend their data. 100 is just plain faster than 10.

Which is better half or full duplex?

Full-duplex Ethernet does save time when compared to half-duplex because it alleviates collisions and frame retransmissions. Sending and receiving are separate functions, creating a system where there is full data capacity in each direction. In contrast, half-duplex can be used to conserve bandwidth.

Is half duplex better than full duplex?

Half duplex mode is a two-way directional communication but one at a time. Full duplex mode is a two-way directional communication simultaneously. ... The half duplex mode provides less performance than full duplex. Full duplex provides better performance than simplex and half duplex mode.
