Before LVOOP, if you did a "find all instances" on a VI, the results would show up in under 1 second. This made "find all instances" a very useful tool to quickly navigate your code. Now if that same VI is a member of a class and is a dynamic dispatch parent or child, LV has to do a complete search of all the VIs in memory which takes forever if you have over a thousand VIs, which is typical on our projects.
