ArcGIS Runtime SDK for Android 和 .NET编辑离线.geodatabase的存储速度问题

ArcGIS Runtime SDK for Android 和 .NET在往离线.geodatabase中写入要素的效率比较低，经测试，相比使用ArcMap从离线.geodatabase转出到GDB的效率慢了几十倍。有没有什么方法能够优化。
下面是.NET的代码例子：

IEnumerable<Feature> LocalBirdFeatures = ...;

string gdbPath = @"...\...geodatabase";

IEnumerable<Feature> LocalBirdFeatures = await flayer.FeatureTable.QueryAsync(new QueryFilter() { WhereClause = "1=1" });

var gdb = await Geodatabase.OpenAsync(gdbPath);

foreach (var table in gdb.FeatureTables)

{

  if (table.Name == "ABC") {//找到指定图层

    foreach (Feature ft in LocalBirdFeatures)

    {

      var feature = new GeodatabaseFeature(table.Schema);

      try {

        foreach (FieldInfo fi in fieldinfo)

        {

          feature.Attributes[fi.Name] = ft.Attributes[fi.Name];

        }

        

        feature.Geometry = ft.Geometry;

        if (table.CanAddFeature(feature))

        {

          await table.AddAsync(feature);//写入比较慢

        }

      catch (Exception ex) {}

    }

  }

}
