So why don't you file a bug attaching one such file please?

Hello again,

I opened a complex dxf-drawing (saved as pdf from SolidWorks).

File A) combined 1700 objects with "Ctrl + K": Inkscape 0.46-->1sec; Inkscape 0.47-->80sec

File B) combined 3000 objects with "Ctrl + K": Inkscape 0.46-->2sec; Inkscape 0.47-->freezes

This really looks like a major bug. I am afraid with these kinds of complex drawings I´ll have to stick to 0.46 until it is fixed.

Can anyone confirm this kind of behaviour?

It is worth submitting a bug, if you attach such a complex drawing and detailed steps to reproduce, as well as information on your OS and hardware.

This would allow to test the case in Inkscape 0.46/0.47 on different platforms. Otherwise it is difficult to confirm your issue.

There are several reports about lack of performance or crashes especially on win32 platforms e.g. when opening/importing big AI/PDF files or ungrouping all objects in PDF or SVG files from Adobe Illustrator with sometimes deeply nested groups and possibly many masks and clipping paths applied. From your description it could be related to (un)grouping as well (because 'Ctrl+K' now works on groups [1]), however that's a only a guess without seeing the original PDF file itself.
