How to create executable that uses mathscript? (LabVIEW 8.2)

Question

Hello all, I have a rather lengthy algorithm developed in MATLAB that needs to be ported to LabVIEW 8.20, with the restraint of having to execute my code in under half a second. If I use the MathScript node/window, I can get the code to run in ~100ms by compiling it in the window and then running the VI. If I don't compile the code before running it, it takes approximately 16 seconds each time I run it, plus some hang up time after it finishes, as if it is closing something. However, it seems that I have to recompile every time I load the project or close/reopen the MathScript Window. My first question is if there is anyway around this, like saving the compiled code to be used if the program is closed and reopened. But in the end, the whole thing must go in an executable. I saw that in 8.20 MathScript code can be built into executables, but the executable that results still takes 48 seconds to run each time. Is this unavoidable? In the build specifications, I've checked the Enable MathScript Support box, and included the code file in the Dynamic VIs/Support Files category and have tried all the options under Additional Exclusions in the build spec window. By compiling the code in the MathScript Window and clicking Save All in the Project Window, there is an option to save a VI that the script seems to have created, which I have also tried to include in the build but received the same results. Any help at all would be greatly appreciated. Thanks in advance,
Chris

Hi Janell, thanks for responding.
The exe does not run any faster if I run it multiple times. I've only
ever run it three times in a row, however, before giving up on that
build.
I've attached a zip of the project folder that includes the m file and
the project/VI files. The exe is also in there in the folder 'Cueing'.
I did make a simple MathScript program that added two numbers and it
ran fine, both using a function call and the MathScript window and just
putting the code in the MathScript node. Both implementations had no
problems, neither did the exe's using either method.
Thanks,
Chris
