  • This statement is misleading in that it says "key generation is expensive". ECDHE key generation (over the elliptic curves that are commonly used for TLS) is insanely fast compared to most other types of key generation.
  • This statement is irrelevant for TLS 1.3, which requires (EC)DHE.
  • Even if this statement is somewhat true for TLS 1.2, it does not justify discouraging the use of (EC)DHE.
