help with speedy graphics

[Geoff Canyon]

After doing this:

   set the markerPoints of grc 2 to 0,0 & cr & 5,0 & cr & 5,5 & cr & 0,5 
& cr & 0,0

This takes about 10 ticks to create 2500 boxes on my machine:

on mouseUp
   put ticks() into t
   put empty into tPoints
   repeat 2500
     put random(300)+410 into x
     put random(400)+50 into y
     put x,y & cr & cr after tPoints
   end repeat
   set the points of grc 2 to tPoints
   put ticks() - t
end mouseUp

As others have suggested, having one graphic for each color should do 
the trick.

Using ten graphics, it takes about 10 ticks to create 10,000 boxes 
using 10 graphics:

on mouseUp
   lock screen
   put ticks() into t
   repeat with i = 1 to 10
     put empty into tPoints
     repeat 1000
       put random(600)+10 into x
       put random(400)+50 into y
       put x,y & cr & cr after tPoints
     end repeat
     set the points of grc i to tPoints
   end repeat
   put ticks() - t
end mouseUp
