So, if it takes three minutes, that's 180 seconds for 10,146 files, or
a merge of about 55 to 60 files per second. I don't think we can
actually consider that a "performance problem".

In version 1.4, Subversion didn't have to think about all that
merging. It simply did it rather blindly. Tracking and figuring out
what to merge was your job. Now, Subversion is doing all the thinking
and tracking for you, so I expect it to take a bit more time.

Maybe there should be some way of "tuning" the merge tracking on a
repository basis. Some people find the merge tracking a godsend.
Others really don't need all of the features, and would like the speed
of the old 1.4 merging algorithm.
