Can you try using the command line so we can rule out Subclipse and/or
SVNKit as causes?

You might want to use the CollabNet Merge Client. It builds merge
client on top of Subclipse. It is EPL licensed and you can get it
here:

http://desktop-eclipse.open.collab.net/

The Subclipse merge has not really been updated for 1.5. It should
still work properly but does not take advantage of newest API's. I'd
highly doubt that is adding any performance problems, but if the
command line does not have the same problem, that would be something
we could look at.

Your validation idea is interesting. Did you do anything to trace the
requests that were being made? I'd have thought that would show up as
network traffic.
