The problem with this data is that it contains a lot of duplicates. If
I cluster the cities into 5103 clusters, I get 47ms. On the other hand
if I don't cluster them, then I get 4.1s. The expensive part is
building the index of indexing on distances. The results are rather odd
- the 500 locations I get have 991 neighbours.
