Seems like a lot of folks missed the section of the post explaining their implementation and use of _ECDHE_ not _EDH_. The performance impact of ECDHE is surprisingly small.
It doesn't help that Apache has a setting "kEDH - Ephemeral (temp.key) Diffie-Hellman key exchange (no cert)" and "EDH - all ciphers using Ephemeral Diffie-Hellman key exchange" that (I think) maps to what IETF TLS calls "DHE - Ephemeral DH".
I get these confused all the time, and now they add in an "EC" prefix!
