For a large enough working set, the more applications request from the file system, the more traffic that there will be over the wire. What does the increased traffic look like? Is it metadata style operations such as GETATTR or LOOKUP or is it data movement like READ? What is the typical working set size, in bytes and numbers of files, of these scripts?
