我今天在我的「ubuntu server 20.04」伺服器上安裝了一個 10Gbit/s 網路卡。但我沒有看到我期望的表現。我安裝的網路卡是asus xg-c100c,是base-t/RJ45網路卡。
我有網路連接,是的,它已連接到支援 10Gbit/s 的裝置(帶有 SFP+ 轉 RJ45 插頭的 Unifi Dream Machine Pro)。
當我執行以下命令時,作業系統似乎也認為存在 10Gbit/s 連線:
~$ sudo lshw -C network
... (some other card are up here)

我嘗試測試我的設定:
- 在兩台獨立的 Windows PC 上使用 samba 啟動副本,均達到 ~55MB/s
- 在一台 Windows PC 上使用 samba 啟動副本,同時在我的 MacBook 上啟動 scp 命令,兩者都達到相同的 ~55MB/s
我複製的內容位於 Samsung M.1 SSD 上。
難道我做錯了什麼?我是否需要更改作業系統才能處理 10Gbit/s?
答案1
我找到了這行不通的原因,這是一件令人悲傷的事。對於那些和我遇到同樣問題的人來說,UDM-PRO有一個10Gbit/s SFP+端口,但從SFP+到RJ45端口的總線接口只有1Gbit/s。這裡有一個圖表。
