換成50M/3M後(VDSL2 MODEM P874同一台,接的VDSL Switch也沒換,問機房端的)

可是ping從15ms降到6~7ms,很明顯是設定檔做更改即可達到降低Latency....

而且改的並非Actual Delay這個值....很明顯可以看出前後是一樣的....

既然調整設定檔案即可降低Latency,為何不做?

但是最大速率變低了不少

VDSL Port Details Upstream Downstream
Line Rate: 3.057 Mbps 25.089 Mbps
Actual Net Data Rate: 3.008 Mbps 25.022 Mbps
Trellis Coding: ON ON
SNR Margin: 31.6 dB 32.3 dB
Actual Delay: 5 ms 7 ms
Transmit Power: - 3.2 dBm 6.9 dBm
Receive Power: -11.5 dBm 1.2 dBm
Actual INP: 18.0 symbols 26.0 symbols
Total Attenuation: 8.3 dB 5.6 dB
Attainable Net Data Rate: 48.755 Mbps 141.208 Mbps

100年5月 第二批P874
VDSL Port Details Upstream Downstream
Line Rate: 3.251 Mbps 54.492 Mbps
Actual Net Data Rate: 3.200 Mbps 54.397 Mbps
Trellis Coding: ON ON
SNR Margin: 31.0 dB 25.9 dB

Actual INP: 17.0 symbols 26.0 symbols
Total Attenuation: 6.5 dB 7.2 dB
Attainable Net Data Rate: 31.047 Mbps 123.864 Mbps

速率的部分speedtest不管怎麼測都只在48M/2.9M左右

hinet測速一樣.......難道是PPPOE鎖50M,電路開54M.....

我是說我沒有付任何專案費，這邊也只有我一戶在用 FTTH。

您的那些官方說法 (或者說是員工角度說法) 只是個搪塞大眾的方式而已。
