We're considering changing our public folder design and want to stress-test the proposed design in our lab to see what effect the changes will have on performance. Does Microsoft offer a tool for this purpose?
Microsoft doesn't offer a specific tool for stress-testing public folder access, but you can use two familiar tools, Microsoft Exchange Load Simulator (LoadSim) and the Exchange Stress and Performance (ESP) tool, to achieve the same result. LoadSim simulates Messaging API (MAPI) clients. You can use this tool to set up a LoadSim user profile that doesn't perform any typical messaging but does make the correct number of public folder requests. The ESP tool lets you use Network News Transfer Protocol (NNTP) and WWW Distributed Authoring and Versioning (WebDAV) to do the same thing for public folder traffic.
