Nir Aides <n...@winpdb.org> added the comment: A link to ccbench results comparing old GIL, old GIL with long check interval, new GIL and BFS: http://bugs.python.org/file17370/nir-ccbench-linux.log
Summary: Results for ccbench latency and bandwidth test run on Ubuntu Karmic 64bit, q9400 2.6GHz, all Python versions built with computed gotos optimization. Old GIL: Hi level of context switching and reduced performance. ~90ms IO latency with pure Python CPU bound background threads and low IO bandwidth results. Old GIL with sys.setcheckinterval(2500) as done by Zope: Context switching level back to normal. IO latency shoots through the roof. ~950ms (avg) is the maximum recordable value in this test since CPU load duration is 2sec. New GIL: The expected 5ms wait related IO latency and low IO bandwidth. BFS patch: Behaves. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7946> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
