最近家裡也想要建構Giga lan.
先用家裡兩台on board 的晶片試了一下
PC1 OS:XP 網路晶片: Realtek RTL8169/8110 Family Gigabit Ethernet NIC
PC2 OS:FC8 網路晶片: Realtek RTL8111/8168B PCI Express Gigabit Ethernet

D-Link 10/100M 5port：
[ ID] Interval Transfer Bandwidth
[1852] 0.0-120.0 sec 131 MBytes 9.12 Mbits/sec
[1732] 0.0-120.0 sec 141 MBytes 9.82 Mbits/sec
[SUM] 0.0-120.0 sec 1.32 GBytes 94.6 Mbits/sec


直接用跳線連接：
[ ID] Interval Transfer Bandwidth
[1732] 0.0-120.0 sec 577 MBytes 40.3 Mbits/sec
[1700] 0.0-120.0 sec 577 MBytes 40.3 Mbits/sec
[SUM] 0.0-120.0 sec 5.60 GBytes 401 Mbits/sec

看來 Realtek 還要在加油才行......
