      Description

      The BridgeBridgeTopologie discovery in a big installation of an customer ( over 7000 nodes and 12000 links) is very slow and need sometimes hours for a single node.
      Picture 1 shows the amount of time that enlinkd needs for the BridgeBridgeTopologie the have 34 active layer2 interfaces. The other Protocols (cdp and lldp) are as fast as usual.
      In a test run with only one Node enlinkd needs only seconds for the discovery (Picture 2).
      I add the logfiles of enlinkd, eventd and the output.log.
      The JDBC-Errors in eventd.log seems to be caused by reimport form a big amount of Nodes with the REST-API.
