Programing in LabVIEW becomes so slow , If i try to connect a single wire its taking 5 sec delay i dont know why please give me some suggestion how to make it faster because IN using more than 200 controls for my project so please kindly let me know any suggestion to make it faster as with this speed we cant finish the project in time.

That does sound like nightmare code. with that many booleans. When LabVIEW becomes sluggish on a very large project you probably should have split some functionality out to component libraries that have defined interfaces. (And those would be testable) Beyond a huge restructuring, the best advice is to change the default Opions setting for maximum number of undo steps from the current 99 to the historical default "9." That undo stack takes a lot of memory with bloated vis and unstructured projects.

You should consider using the Arrays and Clusters wherever possible. Also if you want to show controls in the FP try using the Sub Panels, in this was you can breakdown the big VI into smaller VIs and display the controls and indicators whenever required. I believe you are using Tabs, so in this case a SubPanel will work good.
