Comment 3 for bug 252945

I retested today.
Server is
Bazaar (bzr) 1.17dev
  Python interpreter: /usr/bin/python 2.4.4
  Python standard library: /usr/lib/python2.4
  bzrlib: /usr/lib/python2.4/site-packages/bzrlib
and repo format there is: "Shared repository (format: 1.14 or 1.9)"
Client is
Bazaar (bzr) 1.17dev
  from bzr checkout /home/mysql_src/logiciels/bzr_versions/dev
    revision: 4439
    revid: <email address hidden>
    branch nick: dev
  Python interpreter: /usr/bin/python 2.5.2
and repo format there is "Shared repository with trees (format: 1.14 or 1.9)."
I'm logged into my client machine; I have switched off VPN, email, IRC.
I do "bzr branch" to copy a branch located on the server onto my client machine.
Then I do a one-line change to a text file which is 1900 bytes long, and I commit and push:
it generates 98 kilobytes (KB) incoming and 17 KB outgoing (read from the output of "iptraf" and "tcpdump").
I repeat with a second similar change to another file (which is itself 215 bytes long), and I see again 98KB and 17KB.
So it's not 2MB anymore, but it's still 115KB for a one-line diff...
