bad idea to have a so heavy vector map in Grass...
this kind of operation could be much faster in latest GRASS 7.4 than
in any previous versions. Which GRASS version are you using?
Hello Markus,
I'm using 7.4.1 on debian9
But my grass db folder is on a small server (Synology NAS), so may be
the network makes slow down the operation ?
Cheers,
Frank
