Created attachment 76011 [details] sample svg Attach .svg is incredibly slow to resize and rescale. Appears to me to be much faster in 3.6.5
caolanm->thb: any suggestions ?

I can confirm this bug on 4.0.2.1 pre-release / Ubuntu 12.04.2 LTS but not on LO 3.6.5.2. General SVG display performance seems to have drastically decreased with 4.x. See here for a related bugreport: https://bugassistant.libreoffice.org/show_bug.cgi?id=61230

I can confirm this issue with 4.0.1.2 on Fedora i686. The performance of svg, as well as other images (especially big-size images and/or when they are in big documents) is very poor.
