Correct way of adding edges to existing graph

[HamPlanet]

Hi, is there a way of adding edges to existing graph which is fast and is not constantly updating visible graph ?
My scenario is:
1. My plugin creates a graph that have 65k nodes and 0 edges, every node have some custom attributes
2. User filters the graph to about 10k nodes and 0 edges (by nodes attributes)
3. User sets some parameters and run algorithm to add edges
4. Algorithm takes getUndirectedGraphVisible() from graph model and runs LongTask that creates edges

It looks like this:
Graph g = graphModel.getUndirectedGraphVisible();
NodeIterable ni = g.getNodes();
nodes = ni.toArray();
graph = graphModel.getUndirectedGraph();

for (iterate nodes)
if (condition to create edge between two nodes)
graph.addEdge(graphModel.factory().newEdge(source, target, value, false));

But it is pretty slow and it is constantly updating view - wich is not needed until all edges are created, it is also using a lot of memory.
Thanks.

I tested it again and problems starts when i have around 200k edges it appers as if gephi is constantly filtering graph - i can see it in the right bottom corner of gephi, is it because my current view is filtered ? As i said i create a graph with 65k nodes filter it down to about 10k nodes with range filter and run my algorithm.
