Table with data in columns performance

Hello, i am new to Xamarin and i am trying to do a sort of table: a list of a lot of data(so a fluid scrolling is important) divided in columns of the same width in percent(so they adapt to every screen) in a portable way(i i don't know how to write specific platform code), i don't need vertical seperators. Right now i did a ListView binded to my data, my ViewCell has got a Grid, so i am able to use Percent width (with *).
Here is the code in XAML:

<ListView.ItemTemplate>

              <Grid HorizontalOptions="FillAndExpand" >

                <Grid.RowDefinitions>
                  <RowDefinition Height="Auto" />
                </Grid.RowDefinitions>

                <Grid.ColumnDefinitions>
                  <ColumnDefinition Width="3*" />
                  <ColumnDefinition Width="4*" />
                  <ColumnDefinition Width="2*" />
                </Grid.ColumnDefinitions>

                <Label Text="{Binding ip}"
                     Grid.Row="1" Grid.Column="0" />

                <Label Text="{Binding descrizione}"
                       Grid.Row="1" Grid.Column="1" />

                <Label Text="{Binding utente}"
                       Grid.Row="1" Grid.Column="2" />
              </Grid>

        </ViewCell>
      </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

In the linked .cs file i just bind the ListView.ItemSource to a ObservableCollection and i am using HasUnevenRows.
This way i got what i need but the performance is Very poor. I am doing it right or is a problem of slow Labels?

Thank you in advance
