is there a way to get the timing from each goal/target, ideally send that to somewhere, but even just a dump of it would be good start.

pants server

helps a bit on the goal front, but its hard to pick out e.g different compile targets timing from all the parallel zinc lines

nice! any way to break it down at target level to differentiate b/w different libraries compile time?

You can upload detailed stats, including timing, to any server that can receive POSTs.
