ADS<->LIBRA ser IV simulation time differenc

I was quite disappointed when comparing optimization times of my 7-port design with ADS 2004A and ser IV LIBRA ver. 6.6.
Designs are the same in both cases, having 601 points, 18 optimization goals, 25 rounds (gradient opt.) and only 6 optimization variables (just to compare running times). ADS execution time 742.23 seconds versus 242 seconds with ser IV. So the difference is enormous. Can you give me a good explanation ? Why does it take os long time to optimize the same circuit with ADS ?
