Performance was tested on 2 AWS `t4g.xlarge` instances with 4 vCPUs and 5 Gb/s NIC over LAN. `nftables` was used to redirect
UDP stream of `iperf3` to go through the Phantun/udp2raw tunnel between two test instances and MTU has been tuned to avoid fragmentation.
Phantun `v0.3.2` and `udp2raw_arm_asm_aes` `20200818.0` was used. These were the latest release of both projects as of Apr 2022.
Test command: `iperf3 -c <IP> -p <PORT> -R -u -l 1400 -b 1000m -t 30 -P 5`
