CPU-Usage
3D Traceroute uses threads and waitfor-object-style codes to reduce
cpu-usage to a minimum.
Major consumption of cpu time is done for redrawing the 3d-graph.
Set "Render queue minimum" to a higher value to reduce redrawing.
Switch to list view, if you don't need the 3d graph.
Minimize to taskbar, if you don't need it at all.
There will be a peak usage at trace start due to name resolving and some
dns related tasks. This should last only for some seconds and not happen again
during runtime to that target (results are cached).
If you see 100% cpu usage, please
report more details to me.
