Use the performance monitoring tools supplied with Windows Terminal Server to monitor system performance and the effects of configuration changes on system throughput. The most important measurements for performance monitoring are the percentage of total processor time, memory pages per second , percentage of network utilization, and hard disk I/O rates.

A good way to estimate how many users a server can support is to measure system performance with two to five users on the system and then scale the results. This method has been found to yield reliable results.

MetaFrame provides server-based computing to local and remote users through its advanced Independent Computing Architecture (ICA) protocol. When you use MetaFrame, applications are loaded and executed on the MetaFrame server. As the application runs, the MetaFrame server intercepts the application’s display data and uses the ICA protocol to transmit this data to the Citrix ICA Client running on the user’s device. Similarly, the ICA Client sends keyboard and mouse data to the MetaFrame server for processing.

The Citrix ICA protocol provides the following advanced capabilities:

uTransparent support for off-the-shelf Windows and DOS applications

uHigh performance on high- and low-bandwidth connections

uMinimal client workstation requirements

uFull-screen text presentation

uKeyboard and mouse input with data compression

uError detection and recovery

uEncryption

uData compression

uFile system redirection for client drive mapping

uPrint redirection for client printer mapping

uCOM port redirection

uClipboard cut-and-paste support (Windows clients only)

uAudio support

uIntelligent caching of bitmaps

uPersistent caching to disk

uAdvanced algorithms that discard redundant screen changes and optimize display operations
