Issue Details

My front panel is updating slowly. How do I improve its performance? Does overlapping controls and indicators on the front panel slow down my application?

Solution

You can improve the performance of your front panel by taking these steps:
  • Avoid overlapping controls and indicators. When you have overlapping front panel objects, the time needed to redraw them can be up to 100 times greater.
  • Update only indicators that change their value by placing the indicator terminals on the block diagram in a case structure.
  • Disable the option "synchronous display" of all controls and indicators.
  • Refactor the entire interface by using a Tab Control.
