I gave a presentation last weekend at PyCon Hong Kong about it. Here is my slides: http://www.slideshare.net/araujobsd/functional-and-scale-performance-tests-= using-zopkio The good of Zopkio is, we can write tests at once and run it as much as we want in different machines. Also Zopkio depends of Naarad, that can parse a CSV file and create metrics and SLA over those metrics, plot graphs and so on. Pretty nice tool!!! I'm wondering if we could start to test something and maybe show it at AsiaBSDCon and BSDCon(Canada) next year? What do you think? What I need right now would be a list of tests that we want to perform as well as what parameters we would like to take as metrics to compare.
