MySQL SSL Speed

[Bill Harding]

I've setup my web server to communicate with MySQL over SSL, as described in the docs on thsi site. I am unclear, however, as to what performance impact this may have on my queries? Does running MySQL with SSL enabled mean that all of my queries and results are going to be encrypted/decrypted as they are sent (as would certainly be slower), or does it just mean that there is some sort of initial authentication when the connection is first made, then all queries/results run as fast with SSL as they would run without?

Thanks,

P.S. As mentioned above, I setup mysql with SSL per the instructions on this site (I believe it was in chapter 5), so if the answer to this question is "it depends on how I set it up", the answer is "how the docs said, aka, the simplest way possible"
