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.

I had tried more than 5 PCs with XP SP3 OS last week, all have the same result, unless change the language to English on XP or move on Win 7 OS;
