Can someone please help me in this...

Hi guys,

I am trying to find out how many times the formula in the formula node can ececute in 1 sec. The file is as attached. The result that I got is very low (about 1200000 times/sec) and I have been figuring out why. I did not use any express functions.

 I am expecting to get about 4000000 to 8000000 times per sec. My OS is about 1.73GHz

This problem I preventing me from proceeding to the other part of my project. Please help.

Thanks.

how are you coming to the 4M to 8M executions/second?

Are you including the memory re-allocation of the array out of your while loop [if it needs it]?  Or even the Tick-count VI and the math near it?

Even then, are you accounting for the fact that windows can do whatever it wants to the thread execution and delay your program by seconds if another program deems itself more important? (Antivirus does this, some other operations do it, too)

Every time I run your VI, the number gets larger, which to me says the memory allocation is what is taking too much time.

HI,

4M to 8M is based on one of the guys out there in the forum who say he/she ran my program and able to obtain 8 M/sec. As for 4 M, this is the min amount I hoping to generate.

You mentioned that the number gets larger everytime you run the program which you believe the memory allocation is taking too much time, can you suggest what I can do to recify this problem?

Thanks...

I think this might actually be the original.

You're right!  That was the thread I was looking for because I replied into.  I did a search on the user's post to refind it and came up with the wrong one.  It didn't occur to me there was a third thread that had almost the same title as the one I was looking for.
