Speed up ListPlot3D

Hi Experts,

I work up about 25000 datas of one surface. To show these datas {x,y,z} I
use a package of the following book:
"Mathematica Graphics: Techniques and Applications"
 TELOS/Springer-Verlag Publishers, 1994
 ISBN 0-387-94047-2

To load this package...

Needs["ExtendGraphics`SurfaceGraphics3D`"];

and to show the Surfaceplot...
ListSurfacePlot3D[xyAsti];

xyAsti is a List of Datas of this kind:

xyAsti={{x1,y1,z1},{x2,y2,z2},...}

To show this Graphic the computer needs a long time.

My question:
Is there any wah to speed up this kind of plot or to speed up generally
ListPlot3D? With what precision does Mathematics 4.0 calculates thes Plots?
Can I reduce this precision in any way? To reduce the datas make me loos
informations about the surface!!!
Probably anybody can give me advice!?

Thank you,

Martin
