Hi Jaxx,
If the new loop doesn't have any function with it's own timing (serial read with timeout for example) then it will most likely starve all of the other loops of processor time. If there's something inside the loop which limits the execution speed, it won't because this is in ways similar to placing a "real" wait function in the loop.
Edit : just re-read your mail
If you're referring to placing a while loop around your entire VI, then this shouldn't really have any effect on the synchronisation at all. It just means that the entire thing will run again and again and again....
End Edit
Hope this helps
Shane.
