hrm, I think it would raise questions if we were picking ciphers outside of the 
recommended list, but how could reordering them cause a difference in security 
length? I'm just suggesting ordering them in terms of performance, since 
apparently Mozilla has deemed them all secure enough.

A 4-5x perf difference also raises eyebrows, and even though no one supports 
openssl 1.1 now, it's only a matter of time. (I also think some users end up 
backporting and running new openssl on old distros in order to grab some new 
optimizations)
