I'm not sure what are you using as energy_performance_preference but I've seen important improvements in scaling speed when using balance_performance instead of balance_power, without the need to set the governor to full performance. I'm in Arch at this moment and can't remember if Ubuntu defaults to balance_performance or balance_power, though.
