Sorry, due to some lack of coffee, I ran a version, where DOD was blocked in buildarray.

Here are updated numbers:

$ time perl examples/benchmarks/stress.pl

real 0m0.786s
user 0m0.590s
sys 0m0.200s

$ time parrot -j stress.pbc

real 0m0.849s
user 0m0.780s
sys 0m0.070s

$ time parrot stress.pbc

real 0m0.953s
user 0m0.890s
sys 0m0.050s

The speed difference is due to 12 DOD runs, which take by far the most time:
