Hi, I'm having a similar problem with a LabVIEW .exe. I have a simple VI that initializes a large list (80000 elements) of IMAQ Image references. This happens in 6 seconds in the dev environment but if I put the VI in a blank project and make it an executable it takes 116 seconds for the same operation. Do you have any idea why this might be happening? Everything runs in the same computer. The VI is attached. Thanks in advance.
