Hi Martin,

Yes, it was very close to the optimal speed my connection can support.

Although I have noticed even bigger updates than 20MB from one revision
to the next of trunk, I also have doubts about this *particular* case
(based on my reading of the log update).  I was just trying to update to
from 106890 to 106891 (using 'bzr pull -r 106891') -- just one
revision up.

I am ready to test with client 2.5b5.

Cheers,
Bake
