Hi Aadil..
That sure shall take quite a long time to get simulated. Well I’m sure you won’t be able to bring changes in the design to reduce the time. But I think you should divide the no. of sweeps, like you could have 10 iterations in one simulation and the rest of the 10 in another. This would at least help you in analyzing half of your results without having to wait for more than an hour.
In addition to this , you could refer to the link posted by Aabid in reply #32484.
