throughput reduction at cellular network
Posted: Mon Aug 02, 2021 7:25 am
I built a VPN server and measured the throughput between server and client.
There are significant throughput reduction at cellular network. Throughput decreased by more than 60% compared to without a VPN connection.
By using WiFi without VPN, average throughput: 119Mbps
By using WiFi with VPN, average throughput: 108Mbps
By using 5G without VPn, average throughput: 100Mbps
By using 5G with VPN, average throughput: 35Mbps
I know that the throughput is lowered due to the encryption process of VPN. However, when connecting VPN server using a cellular network, is there any reason why the throughput is so significantly degraded compared to Ethernet?
The connection was TCP and i used iperf3 to measure throughput.
Thank you for answering. Have a nice day!
