[Qgis-developer] save as spatialite very resource consuming

[Rafael Krucker]

Hello all

I've noticed recently (QGIS 2.0.1, Windows 7 64 bit), that, when I'm 
processing a shapefile as layer, even very small ones, the operation 
'save as spatialite' takes forever. With a small shapefile (1 KB), the 
process of converting takes up to 3 minutes, the generated spatiallite 
is then always around 4000 bigger (4.21 MB). These ratios are the same, 
no matter how big the file is, the time taken enlarges linearly it seems.
When the export is a shapefile again, the whole thing is a matter of 
seconds.
Is this due to some kind of buffering issues or does this conversetion 
simply take that many resources?

Kind regards and thanks in advance for any pointers
Rafael
