=== Release 0.1 - Oct 13 ===
 +
==== Goal ====
 +
* Try out different build options
 +
** See how they affect built
 +
* Try profiling the run-time build
 +
** Time how long it takes on each file/directory during the build
 +
 +
==== Results for Rebuilds with No Changes====
 +
* Looking at the breakdown of the time, it can be seen that dom, browser, content, toolkit, netwerk, and xpcom take up a large portion of the build time
 +
* The remaining 39.3% of the build time is divided into layout, intl, embedding and other 23 different directories
 +

* An interesting and note worthy point in the analysis, is that most of these folders are visited multiple times during the build

* Capture the processes being spawned during build along with its pid, ppid, time, duration, and working directory
 +
* Try identifying the cause for slow Windows build

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.

References:

  1. http://wiki.services.openoffice.org/wiki/BuildSpeedup - OpenOffice.org did something similar

Resources: ted

Bugzilla

A bug has been submitted for enhancement on [Bugzilla].

Project Details

  • Get where time is spent during the build
    • 1 set of data from scratch builds and 1 set of data from rebuilds


  • 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

Release 0.1 - Oct 13

Goal

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

Results for Rebuilds with No Changes

  • Looking at the breakdown of the time, it can be seen that dom, browser, content, toolkit, netwerk, and xpcom take up a large portion of the build time
  • The remaining 39.3% of the build time is divided into layout, intl, embedding and other 23 different directories
Charts

Data from 10 Rebuilds were used to create the following charts:

  • A copy of the rules.mk I've edited from the config folder can be found here: config/rules.mk
  • An interesting and note worthy point in the analysis, is that most of these folders are visited multiple times during the build

Release 0.2 - Nov 10

Goal

  • Capture the processes being spawned during build along with its pid, ppid, time, duration, and working directory
  • Try identifying the cause for slow Windows build

Release 0.3 - Dec 1

  • TBA

Project Data

Contribution Instructions

  • Ideas on how to log the following during build time: pid, ppid, start time, end time, process name, current working directory
  • 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

Project News / Updates

November 2008

11/11/2008 -

  • Managed to get process duration

11/06/2008 -

  • Captured processes from a "do-nothing rebuild"
  • Posted description of CSV log on [Bugzilla]
  • Trying to get more accurate data for Benjamin

11/05/2008 -

  • Found a similar app to [Process Explorer] called [Process Monitor]
    • Captures: pid, ppid, start time, end time, process name
    • Can build log file
  • Posted finding on [Bugzilla]
  • Asking for further directions/hints for project

11/04/2008 -

  • Played with [Process Explorer]
    • Captured: pid, ppid, start time, end time, process name
    • Finding ways to log it

October 2008

10/20/2008 -

  • Redo Pie Chart
    • Used all 10 Rebuild Data
  • Changed the app to generate better extractions from logs

10/17/2008 -

  • Finished making app to extract times from log
    • App breaks down log into 3 files
      • File with all lines starting with 'make' (directory path) and 'real' (time)
      • File with just 1 'make' and 1 'real' line for each time - there are times for multiple 'make'
      • File with just level 1 directory times
  • Adding times up for amount spent in each level 1 directory
  • Created diagram to illustrate time breakdown

10/15/2008 -

  • Creating app to extract time from log
  • Timing the build multiple times for both scratch and rebuilds (aiming for 10 builds each)

10/13/2008 -

  • Timed time spent in each directory
  • Working on extracting the data from log

10/02/2008 -

  • Talked with Ted, guided me to look into rules.mk
  • Continuing testing for timing the build

September 2008

09/30/2008 -

  • Looked through many files and still haven't found where code for timing can go
  • Suspect most options don't affect build speed, except -j and optimize

09/25/2008 -

  • After couple more testing with the build options, starting to notice they don't make a big difference

09/18/2008 -

  • Use time command to time build time
    • ie. time make -f client.mk build
  • Start collecting data

09/17/2008 -

  • Built the first time in 1h 20m
  • Rebuilt second time in 35m with all apps off
  • Talked with Shaver and directed me to thread on shrinking build time
    • Thread talked about /MP command for building in VS -> not useful in my case
  • Dave's suggestion
    • Understand what each part of the build is taking
    • Collect win32 build times from colleagues

09/16/2008 -

  • Talked with Ted Mielczarek, briefly discussed about where to start and how to approach this project.
    • Start by timing how long each make file is
    • Identify which make file takes a long time

09/15/2008 -

  • Created Project page for this project.
