Description
It would be really nice if the Print Composer supported multi core rendering like the map canvas does.
This would speed up things quite a bit =)

Although this feature request is well over 2 years old, I still heartily support it.
My largest-scale QGIS project (http://www.imergis.nl/asp/opentopo3200.asp) now requires 135 hours of rendering time (!).
When multi-core rendering is available in Print Composer, I suppose this could be improved significantly.
Is this very difficult to realize? I assumed that once the multithreaded rendering on screen worked, Print Composer would use this as well...

There are reasons why multi-threaded rendering (MTR) is not enabled for print composer as of now... First of all, MTR makes use of images to store the partial results of rendering, so the PDF/printer output would not have vector graphics anymore. Also, it has been found that there are extra troubles when printing on windows (#10599)
