For my 0.3 I will be doing testing on the Koji farm to determine the optimum build factor for the PandaBoards. Currently it is 2 which is the default for Koji, this currently only allows for one task to be built at a time on board which was good for the guru plug and the beagle board, but not the PandaBoard which has more than twice the potential of the other boards on the build farm.
The idea from Chris Tyler is to take down all but one machine on the build farm and queue a bunch of jobs edit the build factor and watch the time taken for builds and determine what the best build factor is. The package I plan to test this out on is the firefox rpm for arm. I am planning to do testing on this sometime over the next couple of days.
