Yes, I am on Cayenne 3.0 release.

I profiled the test but got a bit lost. Eclipse profiler is not very easy
to use and cayenne is quite complex.

Actually, from my two tests (I set the relation -> slow, I don't set it ->
constant time) I noticed that postprocessAfterCommit() takes much more
time in the first case.

If you have an idea on what to look for in a profile or for a better test,
let me know, I will do the tests.

If you have access to a profiler and willing to profile it yourself,
this will help a lot of course :-)
