Beschleunigen Zeit exportieren phpExcel

Question

Ich brauche eine Hilfe, ich habe viele Berichte mit 10 bis 30 Spalten und 20000 oder mehr Zeilen, mi Treiber ist mongodb und die Ergebnisabfrage ist sehr schnell, aber wenn ein Dokumentblatt mit der Bibliothek PHPExcel erstellen ist zu langsam fünf oder zehn Minuten etwa oder einige Zeit mehr, mein Code hat nur ein bucle:

$row++; 
    $contUser = 0; 
    foreach ($data as $index => $objUser) { 
     $backgroundColor = $colorOdd; 
     if ($contUser % 2 == 0) { 
      $backgroundColor = $colorPair; 
     } 
     $field = $objUser->getFields(); 
     $column = 0; 
     //case 'N°': 
     $sheet->setCellValueByColumnAndRow($column, $row, $contUser + 1); 
     $sheet->getColumnDimensionByColumn($column)->setAutoSize(true); 
     $sheet->getStyleByColumnAndRow($column, $row)->applyFromArray($styleArray);

Nun, mit zu beginnen, nicht für jede einzelne Zelle nicht gesetzt Spalt Styling (wie setAutoSizing true), dass Sie Schreiben Sie .... schreiben Sie alle Ihre Daten und wenden Sie dann die automatische Größenanpassung auf diese Spalte an.

Ähnlich wie bei den Zellstilen .... sie sind alle gleich, also wenden Sie sie nicht auf jede einzelne Zelle an, sondern gelten für den gesamten Bereich, wenn Sie mit dem Schreiben der einzelnen Zellen fertig sind. Wo es die Hintergrundfarbe für eine Zeile ist, gilt für den Zeilenbereich, aber nicht für jede einzelne Zelle.
