title: libXL with php_excel Read Performance
body: <p>I have to read large Excel Files in PHP (>2M Cell). 
  I have tried the PHP Class phpExcel, but the Performance is worse. 
  Now, i found the libXL Libary (<a href="http://www.libxl.com/" rel="nofollow">http://www.libxl.com/</a>) und the PHP Wrapper php_excel for it.(<a href="https://github.com/iliaal/php_excel" rel="nofollow">https://github.com/iliaal/php_excel</a>).</p>
  
  <p>Has anyone experience with the <strong>read</strong> performance and memory/cpu usage?</p>
