`update` command is slow and provides no feedback

[pchiusano]

update sometimes take a long time. It seems like it might be related to patch size, but not sure. It would be nice for starters to just report more output. My guess is that both the initial add is slow #2338 and then propagation is also slow, possibly for unrelated reasons.

Like during propagation, some sort of progress or logging messages might be good.

@pchiusano Can you suggest some library we could try an update on to reproduce this?

Closing this because it refers to the old update process.
