You should switch to an OpenSSH release that was made in the past eight years, we've made a lot of improvements since then. I doubt you'll be able to revert that patch easily - it was part of a major refactoring of OpenSSH and anything that touches the same files later will likely conflict. Finally, I don't understand how that patch could cause performance problems - it is mostly just passing a pointer to connection state down to functions that use it, rather than using shared state.
