what arcpy function does Data/Export Data correspond to?

I need to export an xyEvent layer to a shapefile. It is a big file with about 59000 records. When I used the context-sensitive menu/Data/Export Data option in ArcMap, the export took only a few seconds. However, when I try to implement it in Arcpy, it doesn't seem that I can find the right function that can perform this fast. I've tried

arcpy.FeatureClassToFeatureClass_conversion and
arcpy.CopyFeatures_management

Each one takes minutes to finish. Is there another function I should use? I am using 10.1. Thanks people!
