Comment 3 for bug 1290716

One of my tickets for pkg 'adduser' took 1 hour and 8 mins.
                                  bsb- 15 mins,
                                  imagebuilder-47 mins
                                  testrunner-5 mins
The imagebuild-worker which has 1G RAM had taken 21 mins for apt-get clean in the chroot env. http://pastebin.ubuntu.com/7073343/ .

Another ticket of the same package finished in 33 mins with imagebuild-worker taking just 10 mins.

Increasing the RAM size could possibly improve this timing? Still investigating with some more runs altering configs.
