profile performance and memory for a simple program

[SohamSaha]

I am trying to find the program execution time using the tools-> profile -> performance and memeory, for the simple add function.

in my case, no matter how many times the loop runs (1 or 10000), the time given is 15625. Is there a reason for this particular number?

Thanks.

I have no idea what timing details you're looking at. If you're referring to the Profile Performance and Memory windows, that gives a value of zero across the board.

What exactly are you trying to measure? Trying to measure the time that it takes to add two numbers seems pointless to me.

Hi,

I am referring to the Profile Performance and Memory windows. I need to find out the execution time of a few sub vi's in another program, so I wanted to use a simple program to find out the time, in microseconds, taken to run the program. When I run the code, I see the run time as 15625 (see screenshot) or a multiple of 15625. I am trying to understand what this number is.

you can try to add this to your vi

Hi Soham,

15.625ms is the usual resolution when measuring times on Windows before WinVista (XP and older). Maybe this is what you're seeing?
