What we do at FOSS4G to ensure comparability is to use a script generaring thousants of random bboxes with certain attributes (such as min and max size, included in the data area and so on) and then store them in a csv file. JMeter reads that file during the load, that ensures randomness but also that the various servers do the exact same workload. In theory if we had a long enough series of request it would not matter to actually have a reproducable list, but in practice we cannot afford to have servers run for that long, especially since there are 6-8 servers participating to the effort and the testing server is just one ;-) Cheers Andrea -- Ing.
