50*( 3 * 128 channels + 2 * 100 channels + 10 ch + 25 ch + 50 ch)

But all this doesn't explain the very low cpu-usage. One further thing we
have to consider the display. I'm computing in Zuerich and displaying
in Hamburg over a ssh-connection.
Is it possible, that root is waiting for some X11-messages? If this is the
case, is it possible to generate the ps-file without display the
histograms on X11?
