JavaScript Business Rules

Again I consult about business rules in JavaScript, I have noticed that application performance has declined, the performance is very slow, since migrated business rules from pascalscript to javascript.

If someone could tell me about this, and improve performance, or if this is normal?

can you show your JS script, pls?
you can attach it here or send directly to support@

Could you give me the email address please?

I tell you that I am assigning a component to each table like this:

procedure TdmDatasetsBase.CrearScriptProvidersPorUnicaVez(DataTable: TDADataTable);
begin
Datatable.ScriptingProvider := TDASpiderMonkeyScriptProvider.Create(DataTable.Owner);
TDASpiderMonkeyScriptProvider(DataTable.ScriptingProvider).ScriptableComponent := DataTable;
TDASpiderMonkeyScriptProvider(DataTable.ScriptingProvider).OnError := EcmaScriptProviderError;
end;

Maybe this is the reason for that performance has decreased, or is there another way to do this?

My code for business rules in PascalScript did exactly the same thing, a component assigned to each table.

Thank You.

Can you create a simple testcase that reproduces this performance issue, pls?
you can send it to support@remobjects.com
