Hello, 

I'm exhuming this rather old thread because I came across a related  thread
in the boost mailing list
<https://groups.google.com/forum/#!topic/boost-list/7nCzvkkEXCk>  . 

If I get right, the problem is the same that I'm dealing with. The
initialization of the distance / predecessor maps takes more time than the
actual Dijkstra search because a very small region of the graph is visited.
I guess that it is particularly true when the distance / predecessor maps do
not fit in CPU cache. 

Could you go through the proposed solution? If you confirm that the solution
is suitable, I'll implement it in the bfs / dijkstra visitors.

Bests,
f.
