It's never been the case. bzr tries to use a little data and as few
round trips as possible, but there is a relationship between them.
packing occasionally is necessary to prevent a data * latency multiplier
effect occuring over time; it doesn't happen on every commit, and if
you're working with 3G, turning it off would be a very bad idea.
In short:
- use a smart server (will pack for you)
- or performance will get linearly worse, at approximately 5 * your RTT
per commit.
