MassCore and Windows slow down after installing ipMIDI

Problem

You have installed ipMIDI (http://www.nerds.de/en/ipmidi.html) to connect your network controller (e.g. SSL Nucleus 2), and after restarting the computer, every operation in Windows or Pyramix is very slow.

Solution

ipMIDI is sending datas on the wrong network card, which is seriously slowing the operating system.
Please see this page to configure ipMIDI on the correct network card.
