I had to urgently migrate my working project from OSX machine to Windows10 box, and experienced terribly slow performance on loading magento pages (over 1 minute), with developer mode enabled.
After some debugging, I realized that timing issues came from this method
I had to make my changes fast and somehow continue my work so I just replaced
$this->assign() method with pre-genared head contents of
renderHeadContent and after that I got response time about 2-3seconds.
Did anyone struggled with similar problem before and found any workaround ?
