This is more of a question than me sharing knowledge, but I'm testing the effects of MySQL SSL on replication delay. Interestingly, my tests show faster replication when I enable SSL, versus disable. The slave_compressed_protocol has an effect too, and I get the best result when I use SSL and slave compression in a non-CPU bound test.
The question came up, however, of what SSL Cipher I'm using. I'm not specifying one in my CHANGE MASTER statement, so I'm guessing I'm getting the same default cipher as if I connect with the regular mysql command line client with SSL, which is:
SSL: Cipher in use is DHE-RSA-AES256-SHA
I haven't found any manual pages, or any blog posts where people have discussed this, but what is the best SSL cipher to use for both client -> server type workloads, but also replication?
