RE: Subversion client hangs during long operations

Karen,

You’re a lifesaver! That command seemed to have done the trick. I did have
more questions, if you happen to know. The command that fixed the problem
is:

netsh interface tcp set global autotuninglevel=disabled

I'm a little out of my depth on this stuff. If this fixed the problem, does
that mean that I likely had other network problems (or potential network
problems) of which I was unaware? Everything seemed to be working fine, but
I haven't been using this laptop for very long. If it is likely that the
problem was isolated to Subversion, is there something less 'global' I can
set?

Incidentally, I am not the only one using Vista. There is one other user.
The difference is, he is using a different model, so his network hardware
might be different. Also, he upgraded from Windows XP Pro to Vista whereas
I started with Vista when I installed Subversion. He said he recalled being
prompted about Tortoise when doing the upgrade so that he could run it in
'compatibility' mode or something. I looked into that, but there was
nothing I could do along those lines.

Anyway, thanks again so much. I really didn't know what I was going to do
if I couldn't get this fixed.

Jason

This is a total shot in the dark, but Googling around for Windows Vista TCP
connection hangs I found this:

http://blogs.technet.com/asiasupp/archive/2006/12/14/windows-vista-tcp-auto-
tuning.aspx

Gist is Vista has started to use a TCP extension for high performance that
may not be properly supported by some network devices.  If you've got one of
these in your network, connections may hang.  (Are you the only one using
Vista?)  If this is the problem there is a command listed on that page that
you can use to turn off the new extension and so avoid running into trouble.

If this isn't the problem, I'd be interested in taking a look at your
captured packet trace.  It certainly sounds like there's some pretty
low-level network problem, but not so low as the device drivers since you
see the problem over both wired and wireless.
