Hi, I personally also like Valhalla (c++) [1], which also uses OSM data as input. If you use it as an external microservice it's very efficient.
The OSM pbf are recomputed in tiles (also pbf, but other schema) and it's actually pretty fast. Moreover, Graphopper does not include the matrix API in the opensource version, while valhalla does [2].
