Attach .svg is incredibly slow to resize and rescale. Appears to me to be much faster in 3.6.5
caolanm->thb: any suggestions ?
Getting lots of

here - all called from VclProcessor2D::RenderMaskPrimitive2DPixel. Rendering to a bitmap, then getting the content, converting it to an alpha mask. Extra-slow when going via X server...
I can confirm this bug on 22.214.171.124 pre-release / Ubuntu 12.04.2 LTS but not on LO 126.96.36.199.
General SVG display performance seems to have drastically decreased with 4.x. See here for a related bugreport:

Look at bug 62461 please
I can confirm this issue with 188.8.131.52 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.
The issue (very slow scrolling with svg images) is still there with LibreOffice 184.108.40.206 on Ubuntu 15.10.
- same issue with or without OpenGL rendering
- a bit faster with antialiasing disabled, but still slow
Testing resize of inserted SVG in writer: the speed is equal in 3.6 and 5.4.
Please give it more testing and close as WORKSFORME, if you agree.
