nginx ssl handshake vs apache

[Richard Kearsley]

Hi
I was watching this video by fastly ceo http://youtu.be/zrSvoQz1GOs?t=24m44s
he talks about the nginx ssl handshake versus apache and comes to the 
conclusion that apache was more efficient at mass handshakes due to 
nginx blocking while it calls back to openssl

I was hoping to get other people's opinion on this and find out if what 
he says is accurate or not

Many thanks
Richard
