- Zooming in/out, and scrolling after having settled on an area at 1:1 zoom is much faster in trunk (changing the zoom level is still slow, but scrolling is much more fluent than in stable 0.48.3.1).
- Adding new objects and editing or moving them is unusably slow in current trunk (likely related to bug #906952 and the preciser bbox calculation). It's a bit better in stable 0.48.3.1, which on the other hand is much slower when changing zoom levels, and also when scrolling.

Overall, this is not really a file one wants to manually edit in Inkscape, even with lots of patience (Caveat: I'm not a code developer myself - doing mostly bug triage. Based on my experience my impression is that it is not the high number of objects (22540 objects in the top-level group, many of them (possibly nested) groups again) by itself, but actually the size of the "page" (the width/height and viewBox attributes of the <svg> element: 29'890 x 114'083 SVG user units), which mostly exhausts Inkscape's current capabilities. Even if maximally zoomed out (1%), the diagram can't be displayed completely (on a 15" screen at most about 45% of the height are visible in my test).
