I was experimenting with pcfind and made this simple scene.
i have a few points on a grid and i search foreach one of them to find closest points

i think i must be doing something backwards in order for it to be this slow. shouldnt this be more responsive?
check my demo scene to see for your self

Try setting the “Run Over” parameter to “Detail (only once)”. When it is set to “Points” you are do the work for each point in the second input, for each point in the first input (which is 10,000 times!).

it pretty much looks backwards
all you need is

int pnts[] = pcfind(1,"P",@P,chf("radius"),1);
if (len(pnts)>0){
    v@Cd = 0;
}

int pt = nearpoint(1,@P,chf("radius"));
if (pt != -1){
    v@Cd = 0;
}
