From what I can tell using ProcMon, presently when using the Directory tool to list files (including subdirectories) the Alteryx Engine runs a single threaded process.
When you're trying to find files by checking recursively in large network paths, this can take hours to run.
It would be great if the tools would split up lists of directories (maybe by getting two or three levels down first) and then run each of those recursive paths in parallel.
While it is possible to do this using a custom Python or cmd->PS command, it would be great if this could just be a native part of the application.
