This issue was discovered in a customer environment that has 3DEXPERIENCE 2016X with FP1711. We had a SOLIDWORKS Connector client that had major performance issues. Within the connector explorer interface, if we click on Actions or right-click on a non-cached object, it was taking 45+ seconds for the menu to display. After the object was cached by selecting “Get Latest Iteration”, there was no problem.
Solution : WINRAR was the root cause of the issue. Looks like it was trying to cache or read the objects before 3DEXP software. Uninstalling WINRAR solved the issue and the performance was back to normal.
