Actually I found out that with proper settings I can run a 64-bit "translate.py -Ojit" in 3.0GB. I didn't measure the impact on time --- I expect it to take "a bit longer" to run, but of course much less than if it's swapping. Maybe we need to tweak a bit our default parameters... PYPY_GC_MAX_DELTA=200MB pypy --jit loop_longevity=300 ./translate.py -Ojit I think that tweaks to this environment variable have a direct predictable effect: e.g. with PYPY_GC_MAX_DELTA=400MB it would take 3.2GB (an extra 200MB), but do half as many major collections, decreasing the total time. For reference, running "python2.7 ./translate.py -Ojit" takes 3.4GB. So it means that *with some tweaks* we run not only faster, but consuming less memory than CPython, actually. A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
