Thanks a lot Dmitry,
with the autorefresh turned off it is much much better :)

the time needed for the whole loop. Could you please recomend me some alternative method, or just tell me why is this method so timespending?
Try to set VRMLEngine.AutoRefresh to False. But I think that the real reason of slowdown is recalculating of default normals for every changed indexed face set.
