U11 isometric creation speed

We are trying to upgrade from Openplant U8 to Openplant U11.   We are also upgrading Isometric manager from U8 to U11.

When comparing the software, we found that U11 is a lot slower at creating isometrics.  Isometrics that take ~4 seconds to create in U8 will take ~60 seconds in U11.  It's a big issue when we have 1000's of iso's to drop.

This happens on every machine when we install U11, and rolling back to U8 fixes the speed.

Is there a way to speed up iso creation in U11?
