Reducing size of part

I have a part which is around 9.93MB. It is basically a pattern of a feature. It is patterned around 70 times. I don't really use the features in the part for mating. I have two planes in the part which I use for mating in the assembly. This part increases the load time in my assembly. Is there any way to reduce the size of the part somehow?
