No, there is no need to worry about resources in the future (in fact, aside from some current bugs, Inkscape requires far less memory than before). As it's been known, Inkscape is currently going through a refactoring development cycle. What you pointed out is a known issue and as ~suv had linked, Krzysztof is aware if the problem. However, the current plan is for him to actually work on a critical bugfix we need in Pixman/Cairo before anything else directly in Inkscape. Please don't worry and be patient while things are being worked on (Krzysztof has a lot of the "heavy lifting" to do and he's also in school full time right now).

I've not been using Inkscape for a while lately. Yesterday I made a new drawing and noted a considerable slowdown while moving objects. After some investigation, I found that this is mainly due to bounding box update, i.e. while an object (or a group of objects, but a single one is enough) is moved, its bounding box is drawn as a dashed rectangle around it; when I start moving, the rectangle stays in its original position for a while (and moving is ok), then if I stop moving or after a while it gets updated in the new position and this takes ages! I can't work with such a slow update. I've got a Pentium IV 3.2 GHz with 2 GB of RAM. I know it can be considered pretty old a system, but I run all the software I need on it without any problem. I feel that it should be fairly enough for an application like Inkscape (I never use filters or other graphical features, only technical drawing); and it was, up to few weeks ago. I suspect that the bounding box is continuously recalculated but this is not needed as the object cannot change while moving it; also, calculating the bounding box for a single object should not be heavy at all. So, should I start worrying for Inkscape requiring too much resources for me in the near future (or even present) or can this be simply considered a bug? I can easily trigger it by opening a new document, drawing a couple of circles and a couple of rectangles, selecting all four objects and start duplicating them with the spacebar: after a few duplications my CPU usage goes very high and moving objects becomes a pain. It seems related to how many objects are present in the drawing, which is a nonsense because moving a single object should not depend on anything else but the object itself (I tried with all snappings disabled too, of course).

All of the data generated in your IT infrastructure is seriously valuable. Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
