# Performance
Performance was tested on AWS t3.xlarge instance with 4 vCPUs and 5 Gb/s NIC. WireGuard was used
for tunneling TCP/UDP traffic between two test instances and MTU has been tuned to avoid fragmentation.
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.
