Description

Point Sampling Tool takes a long time to complete for
a large nb of points (~20000) and many layers (~8). I note
that the status message is updated for each point and for each field or layer.
Perhaps this input/output operation slows down the processing a lot.
Could you try not to update the fields at all and perhaps update
the nb of processed points at steps of 100?

(could not find a subproject for Point Samplin Tool in
