tran MC sim result size too big

Hi,

In my test bench, there is tran sim

- the result size is ~ 2GB in corner based sim

- the result size is ~ 100GB in MC sim, even if I set number of point = 1, where I check "save waveform (simulation data)" in the MC option. 

- the standard save option is "selected"

Such a huge size of database block my simulation, e.g, plot the curve or run MC sim with tens of points. 

I want to understand why the size of resut can be so large vs normal non-MC sim? Is there any way to make it smaller?
