        <pre>Description:
The source ODS file opens far slower than the exported XLSX 

Steps to Reproduce:
1. Open <span class=""><a href="http://bugs.documentfoundation.org/attachment.cgi?id=133788" name="attach_133788" title="Example file">attachment 133788</a> <a href="http://bugs.documentfoundation.org/attachment.cgi?id=133788&action=edit" title="Example file">[details]</a></span> (<a class="bz_bug_link 
          bz_status_UNCONFIRMED "
   title="UNCONFIRMED - FILEOPEN ODS: Opening is slower as it used to be in earlier releases"
   href="show_bug.cgi?id=108284">bug 108284</a>) 
2. Save it as a xlsx file
3. Open both documents and compare the opening speed

Actual Results:  
The opening of the ODS file takes around 16 seconds in Lib0 4.4.6.3
Opening the xlsx is a lot faster (8 seconds)

Expected Results:
Should be similar in my opinion
