Converted some very old Arcobjects C++ code to run under 10.3. Tracing a geometric network, and while everything seems to work, the method get_NetworkFeature off of the IGeometricNetwork to retrieve the feature from the EID sometimes takes a few seconds. Don't recall having this issue years ago. Program takes up to a day to trace system. Setting flags and tracing in ArcMap is very fast. The data is in a file database. Perhaps using a sql server database would help? Any suggestions would be appreciated.
