[GRASS-user] performing v.outlier - questions

I´m performing the module v.outlier on LIDAR data. I have approximately 3.2
million points. I imported them via v.in.ascii into GRASS GIS without any
problems. I used GRASS Shell within QGIS.
But during processing the module v.outlier some questions occurred.
1) Is it normal that the tool takes that much time? It needed about 9-10
hours. I think it is quite long.
2) During processing the module, some messages were shown within GRASS shell
that irritated me:
2.1) "WARNING: No data within this subregion. Consider changing the spline
step." --> Has this message any negative influence on the result? I couldn´t
find any information about this warning in the internet.
2.2) The message "here we are" was shown quite often ... see in the picture
3) When the module was finished and I tried to refresh the "Browser",
another warning occurred. It is shown in the following picture. I forgot to
make a screenshot of especially this warning, but it occurred some times
before, so I took one of my stored one...
Many questions, hopefully many answers.
