Taking too long for array indexing

[pushkin]

Hi all.

I am having issue with timely/slow indexing into a large array.

The system is LV 2015 running on Win10.

The problem area in the program is:

The above reading process is all within a loop (time is to be less than 50 mSecs).

You can see my approach to measuring the time take.

With the above configuration as soon as the array is within contention the time for the loop start can be say 20 mSecs.  And also longer than 50 mSecs. 

While the prior stack (index 0) above,  gives < 1 mSecs.

It appears the system is not coping with managing the large array.

Index into the array with a standalone vi is fine (< 1 mSec).

The array is 7000 elements of the below;

Please help ?

Please share the actual VI with appropriate sample data to review/debug.

BTW, the stacked sequence structure is so obsolete, why use it?

Yes, there are some problems in this "code":

• usage of stacked sequence
• atleast two case structures around that sequence
• controls hidden within structures
• wires from right-to left, with lots of bends
• there's no code, just an image of code: we cannot edit/run/debug images using LabVIEW!

Please upload your code, with some example data included!
