比方說我某個iPad 連到家裏的VPN server從Netflix下載電影(或者就是stream 看電影),路線是這樣的:
Netflix server => Cable Modem (download) => Router VPN Server => Cable Modem (upload) => My iPad
速度限製為 Min(cable modem download, cable modem upload)
Comcast/Xfinity internet plan,download speed有各種檔次,最低150Mbps,最高也有Gbps,但upload speed不對稱,一般隻要20Mbps,所以我連家裏VPN ,download/upload speed 都不會超過 20Mbps.
光纖internet上下基本都一樣,都超過Gbps,用家裏的 router VPN server比較爽
