Comment 11 for bug 1052502

Ok, comparing 2 builds

https://android-build.linaro.org/jenkins/view/All/job/linaro-android_origen-jb-gcc47-samsunglt-tracking-blob/18/
jenkins time 2h12m (132m)
real 7m36.007s
real 7m2.529s
real 6039.54 (101m)
rest 16.5m

https://android-build.linaro.org/jenkins/view/All/job/linaro-android_origen-jb-gcc47-samsunglt-tracking-blob/22/
jenkins time 3h17m (197m)
real 26m2.595s
real 10m43.538s
real 6740.36 (112m)
rest 48m

So, we have varying time on all 4 stages of build: seed download, git checkout, compilation, publishing. Of these, publishing provides the biggest absolute variation - 30mins!
