I used the attached files to test on my machines.
in jython root dir:
tar xvf benchmark_scripts.tgz
cd patch
taskset -c 1,3,5,7 ./jython.py -u -r
-r: run all benchmarks specified in ./benchmarks/.run;
I chose a couple of ones from Language Shootout Game with various arguments;
-u: unmarshal; It uses ./benchmarks/unmarshal.py to unmarshal pregenerated .pyc files for
the same set of benchmarks included in ./benchmarks/.run
The machine I used:
Intel(R) Xeon(R) CPU E5-2660 0 @ 2.20GHz
Mem 64GB
Linux 3.2.0-25-generic Ubuntu
result:

It shows that if the supplied arguments are not very small, the array version is noticeably faster.
In PyBytecode, line 46, the comments actually mentions that the field co_stacksize is used to convert PyStack from ArrayList to Array.
Thanks. |
