Comment 15 for bug 1481479

I'm sorry for not being clear in my comments, but what I see is exactly like the behaviour described in comment #6. The only difference is that in my case the operating system is Mac OS Yosemite 10.10.5. 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 number of objects in the file. 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.

Slow text adding and editing. Steps to reproduce:

1. Open attached file
2. Try to add new text. First letter appears in about 3 seconds after typing it, and the next appear after a long wait.

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.
