As far as I know at gigabit speed, half duplex is not used. |
| 4 |
Gigabit ethernet uses only full duplex. |
| 5 |
At least I have never seen a switch or nic which can do 1000hdx. |

If you are not getting the expected speeds, could it be your switch? |
| 11 |
How fast is the backplane of your switch, and how many gigabit ports |
| 12 |
does it have? |
| 13 |
|
| 14 |
Some 100Mb switches with 24 or 32 ports have two gigabit ports which |
| 15 |
make make up about half to one quarter of the expectable blackplane |
| 16 |
bandwidth. |
| 17 |
So, if there are other computers putting load on the switch, the |
| 18 |
performance on the gigabit decreases. |
