I'm trying to generate a profile along a track (bike trail) using the [Profile Tool](http://plugins.qgis.org/plugins/profiletool/) Plugin from QGIS, but it consumes more than 14GB's of RAM so it can't finish it's work.

* DEM: 200m GeoTIFF
* Profile-Line (the trail): 600 nodes, 300km length

Both are already generalized. 

As you can see in the screenshot below, this task consumes more then 14GB's of RAM. I tried that on different PC's and operating systems.

I need an vector graphic (SVG) as output.
Is there an alternative to the Profile Tool or a workaround?
