As I said, you cannot calculate the time, you need to measure it. Here is what you could do to measure the approximate subVI call duration in milliseconds.

(Also, you string should go into a shift register. No local variables needed.)

I recommend to start a new thread.

Your last question seems completely unrelated to what has been discussed here, so appending to a thread already marked as solved is not useful.

(... and please use a descriptive title this time. Thanks!) 😄
