Big topology compound - maximize speed

Hello!
Give me some advices, please.
I read a file with topology data (edges and shells) and try to display it by building a Compound. My method works for small models, by I need to display, for example, model with ~2000 edges and ~100 000 shells, and in this case all actions on model (rotation, zoom) are too slow. For model with ~70 000 edges and ~500 000 shells problem is not only in bad performance: after displaying (image appears) program crashes.
I build topology this way:
myAISContext->CloseAllContexts();
BRep_Builder builder;
TopoDS_Compound Comp;
builder.MakeCompound(Comp);
while (lines.MoveNext()) {
(*lines)->GetData (id, nd1, nd2);
builder.Add (Comp, BRepBuilderAPI_MakeEdge (gp_Pnt(nodes[nd1].x, nodes[nd1].y, nodes[nd1].z), gp_Pnt(nodes[nd2].x, nodes[nd2].y, nodes[nd2].z)));
}
while (pols.MoveNext()) {
(*pols)->GetData (id, ndc, nds);
BRepBuilderAPI_MakePolygon P;
for (int i=0; i P.Add(gp_Pnt(nodes[nds[i]].x, nodes[nds[i]].y, nodes[nds[i]].z));
builder.Add (Comp, P.Wire());
}
Handle(AIS_Shape) white = new AIS_Shape(Comp);
myAISContext->SetDisplayMode(white,0);
myAISContext->Display(white,Standard_False);
May be, I'm doing something wrong? Or there are better ways to do it? May be, it will be better to use 3d primitives?
Just in case, I specify, that I need: display a lot of edges (like lines) and a lot of shells (like polygons) with the possibility of selecting vertices (points, from which I build topology), edges and shells.
Thanks for any help!
