Thanks for reporting that. This difference could be only explained by the
server-side delays (for the client there is no difference in trunk or branch
checkout in case amount of files is more or less the same).

So, please get a debug log as I described - it will help to understand how
much time is spent on the server and how much is on the client side. I will
probably have more questions/tests for you after I'll get this log. Thanks!
