[OSRM-talk] Clarification about "shortest path"

I successfully use OSRM for months, and I would like to thank the 
developing team for this wonderful project.

I have always wondered if the "viaroute" query in server API actually 
computes shortest path (distance) or fastest path (time).

The official github wiki says "shortest", but this page 
(http://wiki.openstreetmap.org/wiki/Routing/online_routers) says 
"fastest". When I compare results with YOURS, OSRM seems to compute 
fastest paths. Then, is there a way to compute real shortest paths ? 
Will alternative routes be a mean to get correct shortest paths ?

Thank you in advance,
