B4J Question XmlSax parser seems very slow / long delay

Hello all,

When parsing an approximately 4KB XML file with the XMLSax parser library, it takes around 1 minute to complete.

I'm wondering if there's something I'm missing (likely), or if there's an issue specific to my system.

Please see pasted code sample below.

Thank you for your time!

B4X:
#Region Project Attributes
   #MainFormWidth: 600
   #MainFormHeight: 600
#End Region

Sub Process_Globals
   Private fx As JFX
   Private MainForm As Form
   
   Dim Tidy As Tidy
   Dim Sax As SaxParser
   
End Sub

Sub AppStart (Form1 As Form, Args() As String)
   MainForm = Form1
   'MainForm.RootPane.LoadLayout("Layout1") 'Load the layout file.
   'MainForm.Show
   DownloadQuote
End Sub


Sub DownloadQuote
   Dim j As HttpJob
   Dim dt,dt1 As Long
   
   j.Initialize("", Me) 'name is empty as it is no longer needed
   j.Download("http://livewatch.lebanonema.org/")
   Wait For (j) JobDone(j As HttpJob)
   If j.Success Then
       
       Tidy.Initialize
       Tidy.Parse(j.GetInputStream, File.DirData("LiveWatchMon"), "temp.xml")
       
       
       dt=DateTime.now
       Try
           Dim In As InputStream = File.OpenInput(File.DirData("LiveWatchMon"), "temp.xml")
           Log("start parse")
           Sax.Initialize
           Sax.Parse(In, "sax")
           In.Close
           Log("finished parse")
       Catch
           Log(LastException)
       End Try
       dt1=DateTime.now
       
       Log((dt1-dt) / 1000)
       

       
   End If
   j.Release
End Sub


Sub sax_StartElement (Uri As String, Name As String, Attributes As Attributes)

   Log("start element")
   
End Sub


Sub sax_EndElement (Uri As String, Name As String, text As StringBuilder)

   Log("end element")
   
End Sub
