Re: (severe) performance issues

[Bobby Jack <bobbykjack yahoo co uk>]

My results with the following:

   * Intel P4 3.2 GHz
   * Onboard graphics controller (this may well be the
limitation)
   * GTK 2.10.8
   * Test program defaults (50 labels, 100 FPS)

are CPU usage consistently above 50%. I can try to
reproduce this on another machine (much slower CPU,
better - although still quite old - nvidia graphics
card) if that would be useful.
