- Why does inkscape respond much slower when moving
grouped/multiple
items via arrow keys vs mouse?
Because while you're dragging with mouse, it does not actually move anything, it just pretends. The change to the document happens only as you release the mouse, and then the delay is the same as when moving by an arrow key. It cannot possibly be different as it's the same code at work.
Well, it is different... but your explanation tells me why. It's only updating the document once with mouse, as opposed to 25 times when I use shift+arrow a bit. =)
1a) Why does it take so long to regain control of objects when
they've
been moved? (once again, those grouped/multiple objects)
I don't know because I haven't looked. I guess updates to the document's SVG code are expensive in general. If you want to help, try to debug it to find out which function exactly takes most of that time.
I'll see what I can figure out this weekend (but my guess is it just related to updating the docs code).
- Why does it sometimes take up to 2 mins to start responding
again
after moving grouped/multiple items (via KB)... longest I've seen by mouse is 20 seconds? (sometimes processor is pegged, other times only using 3%, but still not responsive)
I never saw such response times. Please submit a bug with such a file attached. Especially if mouse/keyboard delays are demonstrably different.
Well, my issue is irrelevant, as it appears the delayed response is probably just due to number of updates as above.
Thanks for answering!
