best format for network + Launchpad SFTP?

[Hendy Irawan]

Hi,

What is the best branch format in bzr 0.90 for Launchpad and SFTP 
operations?

The man seems to imply that dirstate-tags is the best format. So I 
upgraded it then do a bzr push... However, it says that there's no 
revisions to push.

If so, how do I make sure that the Launchpad branch is using the new 
format ? Is push --overwrite good for this? Or I have to recreate the 
branch from scratch?

And most importantly, will dirstate-tags help the network performance? 
Thank you.
