Performance Test

Build Perfomance Data

Script used for running the builds: (dylan/master branch): scripts/contrib/build-perf-test.sh

Test systems:

System1: SandyBridge i7-2600 CPU @ 3.40GHz HT-enabled (4 cores/8 threads),  8GB RAM,  1 x 500 GB HDD, Ubuntu 12.04 x64 (with all updates available installed)
        System settings are distro's default:
              - FS mount options are Ubuntu's default: ext4 rw,relatime,user_xattr,barrier=1,data=ordered
              - IO scheduler: cfq (default) and CPU governer: ondemand (default)
System2: IvyBridge i7-3770K CPU @ 3.50GHz HT-enabled (4 cores/8 threads), 32GB RAM,  1 x 1 TB HDD, Fedora 18 x64 (with all updates available installed)
         System settings are distro's default:
              - FS mount options are Fedora's default: ext4 rw,seclabel,relatime,data=ordered
              - IO scheduler: cfq (default) and CPU governer: ondemand (default)

1.4 Performance Data

- Up until 1.4_M5: http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/tree/scripts/contrib/build-perf-test.sh?h=stefans/perf-test

- After that the script has been merged in master, you'll find it in scripts/contrib/build-perf-test.sh
