Routing still fails with large scale requests, using this movements file:

Potential solutions:

• [x] Further improve calculation speed. @xivk
• [x] Increase gateway timeout in NGINX config. @xivk
• [ ] Split requests into multiple one-to-many requests. @pietervdvn

Increasing gateway timeout fixes this issue but it causes the UI to freeze for significant amounts of time.

This commit is what fixed this: https://github.com/anyways-open/deployment/commit/cc7a269b930dbbe1b3e133cef5247c45d8156fca

Potential speed-ups:

• [ ] Group together identical coordinates and translate back to original requested matrix afterwards.
• [ ] Implement a snapping cache: https://github.com/itinero/routing/blob/develop/src/Itinero/Algorithms/Search/Cache/ResolverCache.cs
• [ ] Use multiple threads, currently the calculation uses a single core only while it can easily use multiple.
