Memory leak in BindingSource when using in windows form

I declared the BindingSource inside the form designer, when I run the form without any other controls the CPU memory is more than normal one. For example, if I run the form without declaring the BindingSource object, it takes less than 10% of CPU memory. But after declaring and initalizing the binding source like below, when run the form it takes more than 15% of CPU memory. How can I properly using the SindingSource

The code for initializing the BindingSource,

<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class Form1
    Inherits System.Windows.Forms.Form

    'Required by the Windows Form Designer
    Private components As System.ComponentModel.IContainer

    <System.Diagnostics.DebuggerStepThrough()> _
    Private Sub InitializeComponent()
        Me.components = New System.ComponentModel.Container()
        Me.ClassfileBindingSource = New System.Windows.Forms.BindingSource(Me.components)
        CType(Me.ClassfileBindingSource, System.ComponentModel.ISupportInitialize).BeginInit()
        Me.SuspendLayout()
        '
        'ClassfileBindingSource
        '
        Me.ClassfileBindingSource.DataSource = GetType(WindowsApplication2.Classfile)
        '
        'Form1
        '
        Me.AutoScaleDimensions = New System.Drawing.SizeF(6.0!, 13.0!)
        Me.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font
        Me.ClientSize = New System.Drawing.Size(631, 437)
        Me.Name = "Form1"
        Me.Text = "Form1"
        CType(Me.ClassfileBindingSource, System.ComponentModel.ISupportInitialize).EndInit()
        Me.ResumeLayout(False)

    End Sub

    Friend WithEvents ClassfileBindingSource As System.Windows.Forms.BindingSource

End Class

And the code for the binding class is below,

Public Class Classfile

    Private id As Integer
    Private name As String

    Public Property ID1
        Get
            Return Me.id
        End Get
        Set(value)
            Me.id = value
        End Set
    End Property

    Public Property Name1
        Get
            Return Me.name
        End Get
        Set(value)
            Me.name = value
        End Set
    End Property


End Class
