A few month ago, I wrote an article about some PHPExcel performance tweaks. Sadly we encountered some nasty memory exhaustion issues while reading big XLSX files with PHPExcel. The issues does not occur directly in PHPExcel, furthermore the current PHP process is killed in the SimpleXML/LibXml library execution silently, without any exception or error notification.
When browsing the Vagrant 1.8 Changelog file I realized that the latest Vagrant version supports Linked Clones which according to the Changelog means that imports during the vagrant up process will run much faster than before.
