This is a plot that shows how the data is spread:

I have sorted the timings for each run and plotted the results so that the 1st quartile is a 0.25, the median value at 0.5, and the 3rd quartile at 0.75. I guess the graph shows that the data is alright: most data values (the lowest 75% or so) are close together around the median. About 10% of the data is much larger than the rest, but those spikes are probably the result of network congestion between the three machines. The bazooka machine is a shared webserver and it normally has a load of 5-10, but I've also seen it go to 20+ at times. -- Martin Geisler
