Features

VLESS & XTLS combination has greater performance by reducing the cost of repeated TLS encryption and decryption, especially on hard router (it's measured to double performance), and theoretically more power efficient on mobile devices. However, the improvement is not significant for devices with adequate performance, so you can test it yourself and follow up with future updates, as XTLS will continue to be upgraded.
