The PowerDesigner repository proxy is an optional program that receives requests from client workstations and translates them into a more efficient proprietary format for communication with the repository server. The proxy can considerably improve performance, particularly if clients will be connecting over a WAN or complicated LAN environment or when dealing regularly with larger (15MB+) models, due to its client request pooling and sophisticated caching.
You should install the proxy on the same server as the respository, if possible, to optimize communication between the components. If the repository server processor is not a Windows server or is unable to support the additional workload, then we recommend installing the proxy on another machine on the same LAN segment. We recommend as a minimum, a dual-core machine, with 2-4GB of RAM, but the exact system requirements depend on the number of concurrent users and the size of your repository.
The repository administrator will set up the repository proxy.
