After ungrade to LabVIEW 2012 from 2011, the execution time doubled on XP OS

[ELI2011]

Symptom: After upgrade the source code to LabVIEW 2012, the execution time is 300s while previous is 150s with LabVIEW 2011.

Debug:

a. Move .exe to Win 7 OS, the symptom disappeared;

b. Move .exe back to Win XP OS, and remove commands(in script refer to below image) which will produce large amount of response that exceed 160k, the symptom disappeared;

    

c. Keep all the same, but change area to English from Simple Chinese on XP OS, the symptom disappeared;

Question:

From website http://www.ni.com/labview/os-support/zhs/ we know that LabVIEW 2012 support Win XP, so why has such difference between different languages?

pls advice.

It is hard to say.  I'd suggest running the code in source, and using some kind of timing probe to see where the time difference is.  Or use the Tools >> Profile >> Performance and Memory and see what VIs are taking more time to execute than in the other environment.

No significant differences found from "Profile Performance and Memory", refer to attached .zip file.

Besides, I found the string property has long time delay when transfer large size string to it, on Chinese XP.

Still need understand the root cause about this behavior, I would really appreciate any help on this.
