The best way I've seen was when the FA's announced that we were a bit behind schedule and some passengers had very tight connections. They requested everyone to remain seated to allow those with connections leaving in under 45 minutes to leave first. People (for the most part) listened and those who got up first, got up and moved their butts. The rest of us then deplaned by rows, front to back, as normal.

That let the people who were in a race against the clock get out and start running for their connections while the rest of us could be polite and let people out of their seats without delaying someone behind us.
