If you haven't tried this already, try creating a brand new VI and pasting the contents of the offending VI into the new one.

Just to clarify a bit, that means the block diagram contents, not the front panel!

hey Crossrulz,

You are right,so the code goes to 7.4, the code in't quite complex but yes, quite a lot of duplicated code which unfortunately i cannot find out a way to avoid that duplicate right now, 

I tried to decrease the limit but seems no obvious change.

That pretty frustrating

I actually tried to delete some VI and i can see the slow problem can be avoid significantly. 

that's say it is a problem with my code structures, 

but all my other if case have almost the same structure as i posted in the first page, 

there is no several layer vi in those two if case

Step one would be to create a sub-vi of that code so you only have a few instances of a vi.

2 options:

1. For things that are the same in every case of a Case Structure, it should be moved to be outside of the case structure.

2. Other random duplicate code should be turned into a subVI which you can call from many places.

Both of those will help reduce your complexity.
