Measuring Performance of TeamBuild Build Process

The enterprise builds are huge and take a significant amount of build time. MSBuild offers an option to track the performance of each task and target executed in the build process which would be quite helpful for builders to identify the performance problems and improve the build time. I’m attempting to provide some details on how this can be plugged into TeamBuild.

MSBuild loggers have an option called PerformanceSummary to log this data. The user will need to add the following command line option to the msbuild process that runs on the build machine (refer here for more details on how to pass additional options to msbuild command line in TeamBuild):

/logger:FileLogger,Microsoft.Build.Engine;logfile=buildperf.log;encoding=Unicode;performancesummary

This creates the build log file that contains performance data buildperf.log at <builddir>\<teamproject>\<buildtype>\buildtype on the build machine. Currently, I could not find a way to upload this to drop location, because it needs to be uploaded after msbuild process exits and we currently don’t have a way to do this. BTW, this option is enabled in 'diagnostic' mode. So, user can pass '/v:diag' to msbuild command line and get this data in BuildLog.txt itself. It will have lots of other noise though.

Here is a snapshot of the performance data that msbuild process would log:

The first section gives details about the time taken to complete each project. The 2nd section gives details at an indiviudal target level and the the final secion explains about average time taken by each task.

In the above example, the end-to-end build took 18.549 secs to complete from which Get action took 3.976 secs, creating workspace took 2.354 secs, gathering changesets took 5.318 secs and the actual compilation took 1.332 secs.

Namaste!
