New install of Appcelerator Studio 3.3.0. On first launch, it prompted me to download the new SDK and components (CLI, Alloy, Code Analyzer, etc). Before each and every component is installed, Studio runs npm cache clean. That process takes tens of minutes to run, each time. Running that same cache clean command at the command prompt takes 15 seconds at most. So far, this upgrade process has been running over an hour and it's still working.
