Ben -

Thank you  for the speedy reply:

Actually, there are 2 machines. One, running on OSX. I used as
'storage'. All " bzr branch ..."  going from there,
and all 'bzr push' going there... . The output of 'bzr --version ' on
that machine is :
"
 Bazaar (bzr) 2.1.1
 Python interpreter: /usr/bin/python 2.6.1
 Python standard library:
/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6

 bzrlib: /Library/Python/2.6/site-packages/bzrlib

The second machine --- is Linux, Fedora 13 (64 bit). That is a  '
working machine':
The 'bzr --version ' there is:
"

Good question. I did not think about it until version 93...
(Everything was moving fast, and quick.... ).

The total size of all files -- text files, actually -- 4.5 MB.
I do not know how to estimate what should be the size of 93 revisions?
Assuming all files are text files...

If I understood the question correctly -- the sftp is used.
The actual command is:
bzr branch sftp://michael@xx.xx.xx.xx/home/tst
...
bzr commit
bzr push sftp://michael@.xx.xx.xx.xx./home/tst
  -- or --
bzr push

Also ---
1. I notice that the things start to get out of control, after the
size during the 'fetching' start to grow rapidly from rev. to rev:
It roughly doubled from rev. 93 to rev. 94.... Then nearly doubled
again,,, And finally became 1.2 G (?!).
Which makes the time for 'bzr branch ' -- really annoying....

2. At the same time, I run kdiff3 on rev. 93 & rev. 94 dirs... And
there is no any suspicious differences...

I'm a bit puzzled with all above, and any fresh idea what to double
check and to look at would be really appreciated!

Have a great day,
Michael.
