Excel VBA - writing Data from SQL/Recordset very slow - sql

Question

I am trying to write SQL Server data to an Excel sheet but it is very slow. Is there something to optimize? Approximately, 4000 entries at 20 cColumns takes 6-7 minutes.
Database ("freigabe") Module: Connecting to Database and get RecordSet
(this works like a charm)
Private Function ConnectSQL() As ADODB.Connection
Set conn = New ADODB.Connection
conn.ConnectionString = "DRIVER={SQL Server};" _
& "SERVER=xxxxx;" _
& " DATABASE=xxxxx;" _
& "UID=xxxxxx;PWD=xxxxx; OPTION=3"
conn.Open
Set ConnectSQL = conn
End Function
Public Function load(Optional ByVal FieldName As String = "", Optional ByVal fieldValue As String = "", Optional ByVal ComparisonOperator As String = "=")
'wenn fehler return?
'-> Über errorhandler retun rs oder boolen
Dim rs As New ADODB.Recordset
Dim sql As String
Dim contition As String
contition = " "
Dim sqlfrom As String
Dim sqlto As String
On Error GoTo Fehler:
sql = "SELECT * FROM " & TBLNAME & " WHERE storno='0' AND created BETWEEN '2020-02-01' AND '2020-02-15'"
Set conn = ConnectSQL()
rs.Open sql, conn, adOpenStatic
Set load = rs
Exit Function
End If
Fehler:
load = Err.Description
End Function
Get/Write: Build a connection and retrieving recordset. The While loop is taking long. I am skipping text-rich columns (it gets faster but still too long). Showing a load-window so the person doesn't think that Excel "isn't working". After that, the data get's validated (not included).
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
Dim rs As Recordset
Dim k As Integer
Dim i As Integer
Dim startt As Double
Dim endt As Double
Dim rngDst As Range
Set rs = freigabe.load()
Set rngDst = Worksheets("Freigaben").Range("G2")
With Worksheets("Freigaben").Range("g2:Z50000")
.ClearContents
'.CopyFromRecordset rs
End With
Count = rs.RecordCount
k = 0
gui_laden.Show
startt = Timer
With rs
If Not .BOF And Not .EOF Then
.MoveLast
.MoveFirst
While Not .EOF
For i = 0 To .Fields.Count - 1
If i <> 13 And i <> 2 And i <> 10 And i <> 5 And i <> 6 And i <> 0 Then rngDst.Offset(, i) = .Fields(i).Value 'skip unneccessary data and write
Next i
k = k + 1
Debug.Print k & "/" & Count
gui_laden.lbl_status = "Lade Daten herunter: " & k & "/" & Count
gui_laden.Repaint
.MoveNext
DoEvents 'Ensure Application doesn't freeze
Set rngDst = rngDst.Offset(1)
Wend
End If
End With
endt = Timer - startt
Debug.Print "Dauer: " & endt
What I tried:
CopyFromRecordSet -> Application freezes
Test in new workbook -> same
Thank you very much!
