Writing Annotation Features: Performance extremely Slow

I'm writing a tool to delete and write features into feature classes (from a File Geodatabase into a Geodatabase). I have optimized the code which works fast with tables and feature classes. Just found out that it is fairly slow writing records into Annotaion FeatureClass, which I think is because of writing Blob values into Element field.

while ((feature = sourceCursor.NextFeature()) != null)

{

targetFeatureBuffer = targetFeatureClass.CreateFeatureBuffer();

foreach (FieldIndices _fldIndex in _fldIndices)

{

_SrcObj = feature.Value[_fldIndex.SrcI];

if (_SrcObj != DBNull.Value)

{

targetFeatureBuffer.set_Value(_fldIndex.TgtI, _SrcObj);

}

else

targetFeatureBuffer.set_Value(_fldIndex.TgtI, DBNull.Value);

}

_shape = feature.ShapeCopy;

_shape.Project(spatialReference); //project coordinates

targetFeatureBuffer.Shape = (IGeometry)_shape;

targetCursor.InsertFeature(targetFeatureBuffer);

_noRecsAffected++;

}

Is there a faster way of writing Annotation features ?
