Tableau is mostly a single-threaded application. It will generally only use one CPU which will appear as 50% on a dual core or 25% on a quad core.
We are working to make Tableau take better advantage of multi-core CPUs in future versions.
Does current version of Tableau Desktop/Server use advantage of multi-core CPUs.
I am using 9.0
bump - will be building a machine and plan to use desktop on it -- so will Tableau benefit from the new AMD threadripper / zen 2 / zen 3 with many cores, or should I stick to Intel?
