[DUG] Speed of loading a Client DataSet

[John Bird]

I want to use TClientDataSet for data that is NOT in a database.

Just reading the data from a file, eg for 15000 records, takes much less
than a second, but reading the data and inserting several fields into a
client dataset in a simple loop takes a lot longer, eg 6 seconds or more for
the same 15000 records.

The code I am using is like:

    with tbData do
    begin
      append;
      fieldbyname('FieldName1').asInteger:=Number1;
	fieldbyname('FieldName2').asInteger:=Number2;
      fieldbyname('FieldName3').asInteger:=Number3;
      fieldbyname('Name').asString:=Name;
      fieldbyname('Desc').asString:=Desc;
      post;
    end;

I would like to speed this up, as I have seen that reading similar data from
a Database eg with a query is much faster.  Any suggestions to speed this
up?

I already have lines in such as

 tbdata.DisableControls;
 tbdata.EnableControls;

Before and after I start reading the data to stop screen updates....
