Regarding non-synthetic benchmarks, quite recently I've tested pypy as a "backend" to Gentoo's package manager (portage). System was quite not up-to-date, lots of packages and dependencies, this is how much time did it take portage to figure out what to update:

  python2.7: 323.13s user 6.50s system 99% cpu 5:30.59 total 
  python3.2: 271.40s user 6.33s system 99% cpu 4:38.64 total 
  pypy1.9: 168.28s user 5.95s system 99% cpu 2:55.16 total
