Does Intel HT change the way LabVIEW executes the multithreading option?

[DecaGregg]

I'm doing a performance training course, and it seems that turning off multithreading doesn't decrease performance. The manual says it should.

[Andrey_Dmitriev]

Its depends from your code (single-loop application or multiple loops, executed parallel), computer (single processor or multiple processors), etc. Normaly performance changed depends from this setting, but not always....
There are a lot of articles which can be found on the NI web site:
