Running repo browser on this repositry (http://rhino-tools.svn.sourceforge.net/svnroot/rhino-tools/trunk/)
Opening the trunk folder generates 17 requests.
I attached the trace to this email.
As an example, requests 1 and 4, 2 and 5, 3 and 6 are identical.

Is there any way that stuff can be done in pipelined requests or in
separate connections? Checking a revision number and a root URL sounds
to me like it can be done at the same time, one doesn't depend on the
other (but I don't know anything about the svn protocols, so I may be
wrong). Sometimes I see it doing dozens of requests and taking long, but
my bandwidth is barely used, so I guess the main speed problem becomes
network latency...
