The leaf node of R-tree , a file named .osrm.fileindex, was loaded with mmap function rather directly copy into memory

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.

[CodeExplorerQuantumScripter]

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’.

Sincerely appreciate for your help
