Name of Project

Profile the build system

Description

It's a well known fact that it takes longer to build on Windows than on a comparable Linux or Mac machine. We don't know exactly why, however. There have been many theories, but no real data. Profiling the build system would allow us to figure out where all of the time is being spent. The best place to start might be by adding some profiling to GNU Make, to figure out which targets in our makefiles take the most time. From there, depending on the results, profiling could be added to other parts of the build system to narrow down specific bottlenecks.

Project Details

  • Collect Data
    • Get build time info from others
      • Build From Scratch, Rebuild with no changes, using/not using -j4 option, hardware info (RAM, CPU, RPM)


  • The -j4 option is used in the .mozconfig file
  • -j specifies how many concurrent jobs you can run, so for some parts of the tree you get more makes going at once
    • mk_add_options MOZ_MAKE_FLAGS=-j4


Releases 0.1 - Oct 13

  • Try out different build options
    • See how they affect built
  • Try profiling the run-time build
    • Time how long it takes on each file during the build

Releases 0.2 - Nov 10


Releases 0.3 - Dec 1

Project Data

  • Please feel free to fill in the table to help me collect more data
  • YOU WILL BE CONSIDERED AS A PROJECT CONTRIBUTOR FOR PROVIDING DATA
  • you can time your build by adding the "time" command in front of your build command like so:
    • time make -f client.mk build
</pre> </pre> </pre>
