When you xport it has to calculate the distance to each ship in the list, even if the list is aborted. Makes sense of course, since the game as to deny the xport if it's out of range. But the time required increases with every ship on the list, so it appears as if it's doing a separate distance search for each ship. But perhaps the same BFS queue could be used for all of the ships, which would dramatically reduce the amount of CPU use.

This is a problem in games where a lot of ships are in use and people xport a lot. It can cause some serious CPU spikes.

Maybe changeing the defualt CPU priority to Normal rather than High in the server configure tab may make for more balanced cpu activity.
