Title : Overview and Analysis of Overhead Caused by TLS

Abstract:
A common argument against the use of TLS is that it adds overhead.
In this document we illustrate in detail how much (or little)
processing, latency, and traffic overhead TLS adds. Transition to
more secure cipher suites (TLS 1.2 with AES-GCM or ChaCha20-Poly1305)
actually reduces both traffic and processing overhead. AES-GCM
combines security, low traffic overhead, and great performance on
modern hardware. On platforms without hardware support for AES-GCM,
ChaCha20-Poly1305 gives the same benefits. For everything but very
short connections, TLS is not inducing any major traffic overhead
(nor CPU or memory overhead).
