Cutting Cross Sections for 3D Utilities

I currently have seven different UAOs on a job. I have all of their utilities done in 3D using the newest work flow. I am referencing the 3D into my cross sections when I go to cut. I am only trying to cut one utility file at a time for sections because it takes a ridiculously long amount of time. The average time it is taking right now is somewhere around 20+ minutes for one utility file. Is there any way to reduce the time it takes to cut utility sections? I feel like I must be missing some kind of setting or processing option.
