Each operation is slow with working memory more than enough (file 2073 KB)

[Veronica]

Non si può compiere alcun tipo di operazione perché il programma è troppo lento e si "incanta"; dà errore si apre lentamente, fa rallentare anche il resto dei programmi sul pc.
Il file creato è di soli 2073 KB, i requisiti per l'uso sono di coperti più che sufficientemente e la memoria di lavoro è di oltre 500 MB.
Non capisco se ho sbagliato qualcosa nella creazione del file, si tratta di livelli con riempimenti e linee sovrapposti.

Il mio sistema operativo è Windows Vista, la versione di Inkscape è stata scaricata nel mese di Novembre

I do not understand if I have something wrong in creating the file, it is level with fills and lines superimposed.

Could you attach the SVG file in question?

Allego il file in questione

[su_v (suv-lp)]

Reproduced with Inkscape 0.48+devel r9983 on OS X 10.5.8

I gave up trying to just display the full content of the drawing (let alone trying to edit it), on a MBP with 2.4 GHz Intel C2D and 2GB RAM.

More than half of the file are several pattern definitions (close to 20'000 lines!), one of them very huge (lots of paths), one has AFAICT a nested reference to another fill pattern.

Attaching the file with all pattern definitions removed - opens fast and without slowing down the complete system. I would recommend to use simpler custom patterns to fill parts of the paths (i.e. with fewer objects).

(Firefox 3.6 does load and render the file, but not without slowing down to a crawl and blocking all other tabs, so it is not just an issue that Inkscape has with this type of file structure).

Possibly duplicate of or related to
Bug #292407 “Memory explodes on just moving an object”

Attaching file with the (most likely) problematic pattern…

[Veronica (brunni-hotmail)]

Well, thanks so much for the answer, so the problem is due to the "too high" definition that the patterns I used needed?
What if I use only one of them without puttig on more and more levels? Will I see again the same problem because all of the elements?

Still confirmed.
