Windchill Preference - Operation > General > Threshold for Enabling Parallel Processing

Out of the box setting in WC10.2 for Enabling Parallel Processing is disabled.  Has anybody enabled it to improve performance with Creo Interactions to Windchill?  Or better yet, has anybody performed testing to compare the setting at disabled versus what is recommended in CS24192?  I'm curious to know which workflows or transactions between Creo and Windchill you experienced gains.  There is mention of improved performance with Family Tables...if that is true, then it will be easy to justify the recommended setting.
