Fully utilizing all CPU's for a LabVIEW application

Hi All, Have any of you figured out how to harness all of the CPU's in modern machines? Backgroud: I have an application that does a lot of signal processing and it was pegging the CPU of the machine it was originally deployed on for many minutes. As a quick first step we suggested the customer try the application on a new high-end machine. THey did and the preformance improved ... BUT... When we look at the Task Manager >>> Perfomance tab it appears we are not not utilizing all of the available CPU's. This observation is based on the 8 CPU graphs displayed in the Task Manager. The first 4 graphs show very heavy CPU useage but the reamining four graphs show little or no loads. I am guessing that this may be due to LV (8.X) using a default of 4 threads for each execution system. Since the last time we were on-site, I have looked at ...\LabVIEW\vi.lib\utility\sysinfo.llb\threadconfig.vi and it appears all I have to do is run that utility one time and save the config as 8 threads for each execution system. Now before I send someone back to site, I'd like to find out if someone has traveled this road before me and would like to share their wisdom. Thank you, Ben
