I have a polygon feature class that is 170MB in size. Originally it was 708MB but using simplify and dissolve I managed to get it down to its current size. The problem is that at times it still takes forever to process. I created a feature class of 120 buffers and I need to use that clip features from the 170MB feature class. Is there a way I further reduce the size of the 170MB feature class without sacrificing data integrity? I need this to be more for functional. It's been over an hour and the process is only 33% complete and seems to have frozen. Any help is much appreciated. I'm using ArcGIS desktop, Advanced 10.3.1.
