Extreamly slow performance in the Fill method

I think I must have something misconfigured in NetTiers.

I have an account table that has 56 columns and 1700 records. When I run the following NetTiers code:
TList<ACCOUNT> accounts = DataRepository.ACCOUNTProvider.GetAll();

It takes 17 seconds to load.

When I load the same records into you own object from the same sproc: i.e.
Foreach(row in datareader)
{
    Account account = new Account();
    account.name = (string)reader[“name”];
    …
}

It takes .6 seconds
Can someone point me to where I should start debuging this? Is this normal?

I am running NetTiers 2.0 and the Enterprize libs that come with its ziped download.

 

I have the exact same problem.  I know that going throught the WebServiceClient and a WebService adds a low of overhead, but this is crazy.

I generated my solution.  My database has 90 tables with lots of relationship.

app.config:

<configSections>

<section name="netTiersService" type="Survey.Data.Bases.NetTiersServiceSection, Survey.Data" allowDefinition="MachineToApplication" restartOnExternalChanges="true"/>

</configSections>

<netTiersService defaultProvider="WsNetTiersProvider">

<providers>

<add name="WsNetTiersProvider" type="Survey.Data.WebServiceClient.WsNetTiersProvider, Survey.Data.WebServiceClient" url=http://localhost/Survey.WebServices/SurveyServices.asmx />

</providers>

</netTiersService>

I have one form in my windows app with a grid on it.  here is the form load code:

Imports Survey.Data

Imports Survey.Entities

Imports Survey.Data.WebServiceClient

Imports System.Reflection

Public Class TestForm

Dim mContactsList As Survey.Entities.TList(Of Survey.Entities.Contacts)

Private Sub TestForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim start As DateTime = Now

mContactsList = DataRepository.ContactsProvider.GetAll()

Grid1.DataSource = mContactsList

MessageBox.Show(DateDiff(DateInterval.Second, start, Now, FirstDayOfWeek.Sunday, FirstWeekOfYear.Jan1).ToString())

End Sub

End Class

This takes 30 seconds. My Contacts table has 3 child tables, but I would think that is fine. (ContactEmails, ContactPhones, ContactAddresses)

I have 100 contacts.

The web page that was generated for this database loads the same data in a second or two.

I don't think the problem is exactly the same for the original post, but I would recommend reading this post about improving the performance of the WebServiceClient and any web service client for that matter. If the DataRepository.ContactsProvider.GetAll() is the first time the service gets called .net generates a large amount of serialization information for the first instantiation, thereafter the speed increases.
