Hi Internals, This is the first message from Intel's language optimization team. We would like to provide the Python internals developer community with a daily service which will monitor latest committed patches performance regressions against well known workloads. Our aim is to run a multitude of workloads as well as real-life scenarios which the community considers relevant. The service will send daily bulletins containing latest measurements for daily variations and variations against latest stable release run on our Intel-enabled servers. The community's feedback is very important for us. For any questions, comments or suggestions you can also contact us on our mailing list lp@lists.01.org. You can also check our website: https://www.01.org/lp Results for project python_default-nightly, build date 2015-07-24 09:02:02 commit: 3bbd0cbfe836511dd3e05fcc30ffb5bdbfe686ea revision date: 2015-07-24 07:43:44 environment: Haswell-EP cpu: Intel(R) Xeon(R) CPU E5-2699 v3 @ 2.30GHz 2x18 cores, stepping 2, LLC 45 MB mem: 128 GB os: CentOS 7.1 kernel: Linux 3.10.0-229.4.2.el7.x86_64 Note: Baseline results were generated using release v3.4.3, with hash b4cbecbc0781e89a309d03b60a1f75f8499250e6 from 2015-02-25 12:15:33+00:00 -------------------------------------------------------------------------------- benchmark unit change since change since last run v3.4.3 -------------------------------------------------------------------------------- :-) django_v2 sec 1.12735% 7.47953% :-( pybench sec -0.53822% -2.40216% :-( regex_v8 sec 0.61774% -2.32010% :-| nbody sec 1.75860% -0.76206% :-) json_dump_v2 sec 2.13422% -0.56930% Our lab does a nightly source pull and build of the Python project and measures performance changes against the previous stable version and the previous nightly measurement.
