I have exactly the same problem when preparing scientific posters and including scatter plots with thousands of points. This bug is really awful. It's been four years, it's bizarre that this hasn't been solved yet.

I'm using Inkscape to build figures for scientific manuscripts and a frequent occurence is files that are around 1-2 Mb in size because there are hundreds or thousands of identical objects (dots for a scatterplot, see attached file for a test case). Two versions of Inkscape behave very differently: 0.48.5 r10040 works as expected 0.91 r13725 performance begins to degrade with increasing numbers of objects in the file, with a pause between clicking for text editing and a visible effect on screen. In the end, this version is not usable any more for editing pictures containing scatterplots. I also tested the last development version 0.91 r14326 custom and it behaves like the stable 0.91. The main problem and easiest to reproduce is slow text adding and editing. However, selection of objects and movement also show a very large latency. Steps to reproduce: 1. Open attached file 2. Try to add new text. First letter appears in 1-3 seconds after typing it, and the next appear after various latencies. The same file opened in 0.48.5 can be edited, with new added text appearing as expected, almost as soon as it is typed. This bug is very troublesome since I have dozens of figures done with older versions of Inkscape that cannot be edited any more with the newest version.
