ImportEntities slowness

It seems like ImportEntities is very slow now.  Regardless of importing 2 entities or 2000 entities to a new EntityManager, it takes around 2 seconds...

var toManager = new DomainModelEntityManager(fromManager);
// magic happens here... build up a list of entities to copy into entityList.
Console.WriteLine("Importing " + entityList.Count() + " entities " + DateTime.Now.ToString("HH:mm:ss:ffff"));
toManager.ImportEntities(entityList, MergeStrategy.OverwriteChanges);
Console.WriteLine("Done " + DateTime.Now.ToString("HH:mm:ss:ffff"));

results:
Importing 2 entities 11:35:14:8009
Done 11:35:16:7471

Importing 2071 entities 11:35:26:7271
Done 11:35:28:9743

Any idea what I could look for that would cause this?

Thanks!

Not importing from offline storage, just directly from the "fromManager".  The entities in fromManager were queried for in standard ways.  I tried this anyways:

var toManager = new DomainModelEntityManager(fromManager);
var entityList = new List<Entity>();
foreach (var propertyInfo in fromManager.GetType().GetProperties())
{
  if (propertyInfo.PropertyType.BaseType == typeof(EntityQuery))
  {
    var entities = ((IEnumerable)fromManager.GetType().GetProperty(propertyInfo.Name).GetValue(fromManager, null)).Cast<Entity>().ToList();
    entityList.AddRange(entities);
  }
}
Console.WriteLine("Importing " + entityList.Count() + " entities " + DateTime.Now.ToString("HH:mm:ss:ffff"));
toManager.ImportEntities(entityList, MergeStrategy.OverwriteChanges);
Console.WriteLine("Importing 2nd time " + entityList.Count() + " entities " + DateTime.Now.ToString("HH:mm:ss:ffff"));
toManager.ImportEntities(entityList, MergeStrategy.OverwriteChanges);
Console.WriteLine("Done " + DateTime.Now.ToString("HH:mm:ss:ffff"));

Importing 2 entities 23:05:50:3062
Importing 2nd time 2 entities 23:05:52:3902
Done 23:05:53:9682

So, 2.08s first time, 1.58s second time.

Throwing in query gave the same timing results.

var toManager = new DomainModelEntityManager(fromManager);
var q = ((DomainModelEntityManager)toManager ).Customers.With(QueryStrategy.Normal);
q.ExecuteAsync(op =>
{
  var entityList = new List<Entity>();
  foreach (var propertyInfo in fromManager.GetType().GetProperties())
  {
    if (propertyInfo.PropertyType.BaseType == typeof(EntityQuery))
    {
      var entities = ((IEnumerable)from.GetType().GetProperty(propertyInfo.Name).GetValue(from, null)).Cast<Entity>().ToList();
      entityList.AddRange(entities);
    }
  }
  Console.WriteLine("Importing " + entityList.Count() + " entities " + DateTime.Now.ToString("HH:mm:ss:ffff"));
  toManager.ImportEntities(entityList, MergeStrategy.OverwriteChanges);
  Console.WriteLine("Importing 2nd time " + entityList.Count() + " entities " + DateTime.Now.ToString("HH:mm:ss:ffff"));
  toManager.ImportEntities(entityList, MergeStrategy.OverwriteChanges);
  Console.WriteLine("Done " + DateTime.Now.ToString("HH:mm:ss:ffff"));
});

Importing 2 entities 23:29:41:5530
Importing 2nd time 2 entities 23:29:43:4812
Done 23:29:45:0553

Thanks.  I have submitted the solution on ticket #7159
