Sorry to interrupt, there is a question confusing me a lot. In the engine of osrm, R-tree can convert a true location node to a nearest edge based node, which is relying on shortest distance search.

The R-tree is composed of two part, tree node saved in .osrm.ramIndex about 22M and leaf node saved in .osrm.fileIndex about 5G. Why .osrm.fileIndex of R-tree was loaded by mmap way when startup parameter without ‘--mmap’.
