title: PHPExcel taking an extremely long time to read Excel file
body: <p>I'm using PHPExcel 1.7.8, PHP 5.4.14, Windows 7, and an Excel 2007 spreadsheet. The spreadsheet consists of 750 rows, columns A through BW, and is about 600KB in size. This is my code for opening the spreadsheet--pretty standard:</p>
  
  <pre><code>//Include PHPExcel_IOFactory
  include 'PHPExcel/IOFactory.php';
  include 'PHPExcel.php';
  
  $inputFileName = 'C:\xls\lspimport\GetLSP1.xlsx';
  
  //  Read your Excel workbook
  try {
      $inputFileType = PHPExcel_IOFactory::identify($inputFileName);
      $objReader = PHPExcel_IOFactory::createReader($inputFileType);
      $objReader-&gt;setReadDataOnly(true);
      $objPHPExcel = $objReader-&gt;load($inputFileName);
  } catch(Exception $e) {
      die('Error loading file "'.pathinfo($inputFileName,PATHINFO_BASENAME).'": '.$e-&gt;getMessage());
  }
  
  //set active worksheet
  $objWorksheet = $objPHPExcel-&gt;setActiveSheetIndexbyName('Sheet1');
  
  $j = 0;
  
  for($i = 2; $i &lt; 3; $i++)
  {
  ...
  }
  </code></pre>
  
  <p>In the end, I eventually want to loop through each row in the spreadsheet, but for the time being while I perfect the script, I'm only looping through one row. The problem is, it takes 30 minutes for this script to execute. I <code>echo</code>'d messages after each section of code so I could see what was being processed and when, and my script basically waits for 30 minutes at this part:</p>
  
  <pre><code>$objPHPExcel = $objReader-&gt;load($inputFileName);
  </code></pre>
  
  <p>Have a configured something incorrectly? I can't figure out why it takes 30 minutes to load the spreadsheet. I appreciate any and all help.</p>
