For cleartext performance I really don't know for sure what you can do, except maybe using bare metal rather than a virtual machine. Other people have been around this community a lot longer than I have and may have better ideas. Getting that cleartext performance up to a reasonable level will be your first step. Once that's done, there are a lot of things that will help with performance using SSL. This is an AWESOME video on that subject: https://www.youtube.com/watch?v=0EB7zh_7UE4 The current haproxy version implements almost every performance-enhancing method mentioned in that video, as long as your openssl is new enough.
