I test it on xamarin forms ios. 
Adding a swipe and not doing it The scroll list speed is too different.
And adding two swipes is okay, but adding five swipes slows down the list.
The code is shown below.

<telerikDataControls:RadListView.ItemSwipeContentTemplate>
                <DataTemplate>
                    <Grid Padding="0,0,0,5"
                          ColumnSpacing="0">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="60" />
                            <ColumnDefinition Width="60" />
                            <ColumnDefinition Width="60" />
                            <ColumnDefinition Width="*" />
                            <ColumnDefinition Width="60" />
                            <ColumnDefinition Width="60" />
                        </Grid.ColumnDefinitions>
                        <Button 
                            Grid.Column="0"
                            BorderRadius="0"
                            Image="{Binding FavoriteImage}"
                            BackgroundColor="{DynamicResource C_main_lev3}"
                            Clicked="Favorite_Clicked"/>
                        <Button 
                            Grid.Column="1"
                            BorderRadius="0"
                            Image="ic_refresh.png"
                            BackgroundColor="{DynamicResource C_main_lev2}" />
                        <Button 
                            Grid.Column="2"
                            BorderRadius="0"
                            Image="ic_setting.png"
                            BackgroundColor="{DynamicResource C_main_lev1}"
                            Clicked="NickNameUpdate_Clicked"/>
                        <Button 
                            Grid.Column="4"
                            BorderRadius="0"
                            Text="hide"
                            TextColor="White"
                            BackgroundColor="{DynamicResource C_sub_theme3_lev2}"
                            Clicked="Hide_Clicked" />
                        <Button 
                            Grid.Column="5"
                            BorderRadius="0"
                            Text="block"
                            TextColor="White"
                            BackgroundColor="{DynamicResource C_accent_theme1}"
                            Clicked="Block_Clicked" />
                    </Grid>
                </DataTemplate>
            </telerikDataControls:RadListView.ItemSwipeContentTemplate>

Hello SeokYeol,

I have tested this in a basic setup using the example from our documentation (ListView: Cell Swipe) together with the provided code and the SwipeContentTemplate didn't affect the scrolling performance at my side.  I will need some more details on the scenario you have, is it possible to prepare a sample project demonstrating the issue and send it to us?

You should open a private support ticket and attach it there as only image attachments are allowed in the public forums.

Thank you in advance for your cooperation.

Regards,
Yana
