My labview library is taking up about 100MB of space and I do not understand why? There are only about 10 vi's in the library. However I will mention that the array size passed between the vi's is huge (around 100K elements). But I am puzzled because the vi's doesn't know I am passing large array before actually running them so I am not sure why it is taking up so much space. Also the vi runs really slow. Is there any way I can speed it up? I admit I am doing a lot of signal processing. Will it run faster if I turn it into a executable? Thanks a lot
