TLS 1.3 Encryption Standard Moves Forward, Improving Internet Security

Among the multiple improvements in TLS 1.3 is increased speed of operation. A core promise of the new encryption standard is that encrypted traffic will be handled by servers and browsers as fast as un-encrypted traffic. When TLS 1.2 was first defined, only a small fraction of web traffic was encrypted. In 2018, encrypted HTTPS traffic accounts for over 50 percent of web traffic according to multiple reports including one from Cisco.
