Yes, I see that too.  On my machine, 3.7.0 (the older version, I haven't
installed the correct one yet) took 200.4 seconds trace time, while 3.8.0 took
1118.9 seconds trace time.

The model I used for those earlier results is one with many simple objects
(about 19k of them), all but about 50 are opaque.
