We're currently doing a lot of testing of our Tableau server to try to get performance more in line with our client-side baselines. For a couple hundred users we're running Tableau server on a virtual machine that has 4 CPUs and 12 GB of RAM and 500 GB hard drive space, set to allow 4 VizQL processes and two simultaneous extracts. I suspect this is not a good configuration. Would anyone who is getting good Tableau server performance care to share what their hardware configuration is? Thanks.
