Hi Tav and others!
Thanks for your hard work. I appreciate it really. Looking forward to other improvements.
Can you please try Yale`s patch for multithreaded rendering we talked on this list already. I think it is possible to find it in some meiling list thread, but in case you can`t, I`ll find it myself tomorow when I come to my desktop computer. It does wonders on this i7 6700 processor.

Hi,
It's been known for a while that rendering when zooming in on an area with filters is slow. This is due to Inkscape breaking the canvas into tiles and rendering each tile separately. Filter effects are recalculated for each tile that they touch. A typical canvas for maximized Inkscape window on a 1080p monitor is broken into about 25 tiles. If you are zoomed in so that the filter extends over the entire visible canvas, you are recalculating the filter effect 25 times.
I've added a preference under the "Rendering" tab to change the relative tile size (Rendering tile multiplier). Please play with changing the value for your most complex drawings. I am most interested in cases where a large multiplier has a negative impact. If there are no cases with a negative impact, I'll set the default value higher (it is currently 1).
