[GRASSLIST:5545] d.what.vect performance problem

I have a sites map with 500,000 points. I have converted it to a vector
map. d.what.sites retrieves information about the nearest point pretty
much instantaneously.

d.what.vector takes several minutes before it is able to even respond.

Is there any way that I can improve the performance of a d.what.vector
query on a map with a large number of features?

Is there a way of structuring the data to help speed things up?


Thanks,

  Brent Wood
