請教 Gb LAN latency

Gbit LAN -l 65500 既 PING 值大約係幾多 ?

FE LAN latency :

C:\>ping 192.168.0.10 -l 65500

Ping statistics for 192.168.0.10:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 12ms, Maximum = 12ms, Average = 12ms

其實GE同FE個latency, 喺屋企用係唔覺ge
因為你上網嗰段ge latency 先大
數學上, GE ge propagation delay 係 0.012ms, FE 係 0.12ms
慳左 0.108 ms

我用 -l 65500 PING WRT54G 會 time out
