my area (I guess because of topology). I do the same with Qgis
from a shape in less than 10 minutes (but with several
operations)... it's may be a bad idea to have a so heavy vector
map in Grass...<br>

<div>this kind of operation could be much faster in latest GRASS
7.4 than in any previous versions. Which GRASS version are you
using?</div>

<p>Hello Markus,</p>
<p>I'm using 7.4.1 on debian9</p>
<p>But my grass db folder is on a small server (Synology NAS), so
may be the network makes slow down the operation ?</p>
<p>Cheers,<br>
