Performance test

For verify the effect of quic-tun in network performance, I make some tests and wrote this report.

The following three metrics should be focused during testing: Network Bandwidth, Network Latency, CPU usage. We will compare the these performance metrics between transport traffic directly by TCP and transport traffic by quic-tun. We will also make different packet loss rate network environment.

Test environment and tools

• Two local vmware workstation virtual machines, One as server machine, anthor one as client machine.
• One remote machine that can be access by public network, used to test network latency in WAN.
• Operating-system: ubuntu 20.02
• Network Bandwidth test tools: iperf3
• Use top command to watch the CPU useage

Additionally, I haven't find good tool to test Network Latency. So, I use python wrote a test tool myself.

How to set the packet loss rate

VMware workstation support set the packet loss rate for a specified virtual machine, like below:

In all test cases, I just change the client machine's packet loss rate, moreover the incoming packet loss rate and outgoing packet loss rate are same. The server machine don't set packet loss rate.

Test results

• Network Bandwidth and CPU Usage
• Network Latency
