As we’ve mentioned in a previous blog post one of the key advantages of TLS 1.3 is the reduction in round-trips. Older versions of the TLS protocol require two complete round-trips before the client sends the application data. With TLS v1.3 only 1 round-trip is required! This means network latency has less impact on the time required to establish a secure connection. We recently completed a handshake benchmark with various latencies to make sure wolfSSL is taking advantage of the reduced latency in TLS 1.3.
