RE: 1+ hours to merge, can you beat that?

We had problems, when the permissions was set on some subdirs on svn.
If we turned off subdirs permissions and all permissions are set on root of svn over https it is significantly faster.
We had problems, with gettin log message from repository and all others actions, because if there are permisions on subdirs or files, svn over https check every file (may be every revision of file) if user has permission to that.

May be that this is not solution for your problem, but may be ;-)

A ping of a half second is a lot. Basically, this is the time to send one IP
packet to the server and back. If I want to check if a file exists and
retrieve its svn:mergeinfo property, I send a request and then wait for an
answer and if that is positive send another request and wait again. That
means this simple operation would need more than one second already, just for
that single file and without actually doing anything. If you not have a few
hundred files, just checking information already takes several minutes. If
you now add some real work, like retrieving changes, you get even longer
times.

In any case, this network latency might play an important role in the low
merge performance.
