Comment (by karsten):

 I think I found something: I just added `commons-math3-3.6.1.jar` (2.1M)
 to the libs for an unrelated experiment, and the effect on `ant war`
 (which doesn't even use that lib in my experiment) was that it took 97
 seconds as compared to 66 seconds without that lib.

 So, a quick fix might be to look closer which libraries are required in
 the .war file. For example, we could easily remove
 `postgresql-9.4.1212.jar` (636K) from the .war and only use it in the
 .jar. I didn't look much further, but maybe there are other libraries we
 can avoid including in the .war.
