Description Darko Veberic 2013-04-19 06:48:12 UTC 
my default view is page thumbs on the left and fit page on the right. lately, more and more pdfs are quite heavy on processing. pages render slowly and i end up staring at the blown-up thumbs for ages before they are replaced with true renderings. on the other hand, my 4 core cpu never gets above 25% which is somehow a waste of time. is it possible to render pages in parallel on all available cores?

Reproducible: Always

Actual Results:  
slow rendering on one core

Expected Results:  
faster rendering on all cores
