Isn't there a performance burden?
- OptionX 6y agoSupposedly not (vs TCP/TLS), at least not in the Google implementation (haven't read anything about the IETF version). And with 0-RTT, when it comes out, you gain some performance back anyway by not having to re-handshake on drops.
- cma 6y agoThe comparison would be against TCP with no TLS, since the issue was mandatory encryption.
- loeg 6y agoSome, but maybe less than you think if you're using OpenSSL and a computer less than ten years old (AES-NI and maybe PCLMULQDQ for GCM). Often something else (NIC, network) will be the bottleneck.
