Querying time

[Vikas-Sony]

Hi,
I tried building a tree with around 12000 points which took around 7-8 ms.
But querying time for a single point is around 0.01ms or so. I was expecting lesser time than this judging from the fact that whole tree creation took 7ms.
So, i believe the tree may be unbalanced and want to look at created tree structure. Is there an easier way to do that?
Also, what else can i do to reduce my query time as i has to query about 7000 points and needs it to be real time?
Thanks in advance

Also, can i query multiple points at once?
