We have submitted a new draft on TLS overhead. That TLS causes overhead is a common argument regarding TLS (and other security protocols). If TLS adds much overhead has recently been discussed in e.g. GSMA.
In this document we illustrate that for everything but very short connections, TLS is not inducing any major traffic overhead (nor CPU or memory overhead). Transition to more secure cipher suites (TLS 1.2 with AES-GCM or ChaCha20-Poly1305) actually reduces both traffic and processing overhead. I plan to request time for presentation in Toronto.
