Christian,
Yes it is really bad.

As performacne test I create a set of script which did a checkin
every 15 minutes on about 20 branches all to the same file.

The net result was any time did a ct lsh or ct lsvtree or ct find merge
or check in of that file
the whole company froze for 30 seconds to 2 minutes.
