To improve stepping speed, follow these recommendations
  • Turn off Alternate view for Collections classes by clearing the Enable alternative view for Collections classes check box at the Data Views page of the Debugger settings.
  • Turn off 'ToString' mode on the IDE level, by clearing the Enable 'toString' object view check box at the Data Views page of the Debugger settings.
  • Simplify conditions for breakpoints and watchpoints, especially frequently hit ones.
  • Use filters (e.g., for class instances).
  • During the debugging session, switch to a view with fewer elements.
