I have two "experts" telling me conflicting facts. The first expert says the locking down a NIC and switch port to 100 full duplex will make the network go as fast as possible. The other expert says that he has seen better network speed with leaving both ends set to auto negotiate.
Personally to me it seems that 100 FD would give the fastest performance because the devices would not have to “talk” about the speed and duplex rate, but I didn’t want to go through the lengthy process to prove the facts. If anyone has any first hand experience with this question, please include the type of devices you have seen this scenario tested on.
Thank you for your time.
