I am using this version but still issue is not solved Its taking 18 hours and after that throws exception :
Function evaluation disabled because a previous function evaluation timed out. You must continue execution to reenable function evaluation.

This new build now takes about 5 seconds to export a 1500-items diagram to VDX:
https://mindfusion.eu/_beta/netdiag531.zip

On our test system it takes less than 8 minutes to export the 104 pages separately:

// load time: 00:02:08.9703767
// layout time: 00:08:15.4793398
// export time: 00:07:22.7483237

var document = new DiagramDocument();

var startTime = DateTime.Now;
var dirInfo = new DirectoryInfo(@"C:\temp\XML");
foreach (var fileInfo in dirInfo.GetFiles("*.xml"))
{
	var page = new DiagramPage();
	page.LoadFromXml(fileInfo.FullName);
	document.Pages.Add(page);
	page.Title = fileInfo.Name;
}
Debug.WriteLine("load time: " + (DateTime.Now - startTime));

startTime = DateTime.Now;
foreach (var page in document.Pages)
{
	var dl = new DecisionLayout();
	dl.Orientation = MindFusion.Diagramming.Layout.Orientation.Vertical;
	dl.HorizontalPadding = 10;
	dl.VerticalPadding = 10;
	dl.Arrange(page);
}
Debug.WriteLine("layout time: " + (DateTime.Now - startTime));

startTime = DateTime.Now;
foreach (var page in document.Pages)
	new VisioExporter().Export(page, @"C:\test.vdx");
Debug.WriteLine("export time: " + (DateTime.Now - startTime)); 

You still won't be able to fit all 104 diagrams and Visio XML in the process memory, so if you need them merged in the same VDX, try using the .NET XML API to create it. E.g. you could export the pages separately, unload all diagrams to free memory, then copy individual Page element from each exported file to a merged file under the parent <Pages> element.

The latest build here supports hyperlinks:
https://mindfusion.eu/_beta/netdiag.5.4.zip

Set node.HyperLink to either a page name or a web address and VisioExporter will generate appropriate XML markup.
