No, if you change the SQL IBO will do an unprepare automatically.

I know why IBO is faster than the rest. I figured out a way to have less
chatter across the wire. IBX would need to do a whole lot of work to close
that gap, which work Jeff said he wasn't ever going to do.

Keep in mind this benchmark was done across a DSL line so IBO's more
efficient network usage really shines more brightly here. On a LAN and
especially local, there is not going to be a significant difference in the
same benchmark. In fact, IBO is probably a tiny bit slower because it is
doing the little bit of extra work on the client to make things more
efficient on the wire.

In short, I thought it would be very much worth it to have a performance
degradation of 0.01% in a local environment (negligible) in order to gain a
100% improvement on a slow/remote connection (very appreciable).
