Suraj Menon commented on HAMA-704:
----------------------------------

Are these numbers for trunk or with patch?

> is it intended in the VerticesInfo to do a linear search for every vertex? 
> That is slow like hell.
Hence the Collections.sort and binarySearch. We need the check only for 
addition of vertices right?
