Comment 5 for bug 631206

SELECT DISTINCT BuildFarmJob.builder, BuildFarmJob.date_created, BuildFarmJob.date_finished, BuildFarmJob.date_first_dispatched, BuildFarmJob.date_started, BuildFarmJob.id, BuildFarmJob.job_type, BuildFarmJob.log, BuildFarmJob.processor, BuildFarmJob.status, BuildFarmJob.virtualized FROM BuildFarmJob LEFT JOIN (PackageBuild
INNER JOIN (Archive INNER JOIN TeamParticipation ON (TeamParticipation.person = 2 AND TeamParticipation.team = Archive.owner and (archive.private=FALSE or TeamParticipation.person is not NULL))) ON PackageBuild.archive = Archive.id) ON PackageBuild.build_farm_job = BuildFarmJob.id WHERE BuildFarmJob.builder = 3 ORDER BY BuildFarmJob.date_finished DESC, BuildFarmJob.id LIMIT 51 OFFSET 0;

930ms - uses two inner joins rather than left joins.
