Hi,

Can you tell us what that process is?

If this is caused by what I think it is then the smart server won't
help unfortunately.

I can recommend that everyone sets up a shared repository for 
themselves (bzr init-repo dir), it will massively reduce disk usage
and time for some operations.

You need to do this before creating a branch, and then create the branch
inside the directory you create (the dir argument to init-repo). Then
all branches that you create under there will share storage where 
possible.

Jason, did you create these branches in a rich-root-pack format 
repository, or just pack-0.92 (the default with 1.0 or later)?

Thanks,

James
