Strange, I got much better timing on a similiar situation
with transactions... can you try this?

 Dim conn As New ADODB.Connection
  Dim com As New ADODB.Command
  Dim i As Long

  conn.Open "DSN=mydb;uid=username;pwd=mypassword"
  Set com.ActiveConnection = com

  conn.BeginTrans
  For i = 0 To Size - 1
    sql = "update mytable set value1 = " & array1(I) & ", value2 = " &
array2(I) & _
          ", value3 = " & array3(I) & ... & ", value20 = " & array20(I)
& _
          " where code = " & codes(I)
    com.CommandText = sql
    com.Execute adExecuteNoRecords + adCmdText
  Next i
  conn.CommitTrans

Also, have you updated to the latest ADO version (I'm using ADO 2.6)?
Is all logging disabled?
Hope this helps
