As others have mentioned, duplex mismatch is a good cause. If you have a
client with java support, give the NDT a try as this is something it
claims to detect:

There's a master site list available here so you may wish to find a

Caveat: I think most of them are Internet2 only. I know the ANL and CERN
sites are accessible to us but didn't try them all.
