Abstract

Citrix Systems, Inc. commissioned The Tolly Group to evaluate its Presentation Server 4.0 product and its value-add to Windows Server 2003 Terminal Services. The test focused on one specific area of value-add: performance, user experience, and network impact.

Tolly Group engineers measured the number of bytes transmitted and the elapsed time necessary to view a sample PowerPoint presentation over multiple simulated networks varying link speed and latency types with clients implementing either Citrix Presentation Server (on top of Windows Terminal Services)or Microsoft Windows Terminal Services (standalone). Using the same environment, engineers also examined the average network throughput achieved when copying a file between a server and a remote Windows XP client. Finally, The Tolly Group measured the throughput achieved when performing a remote printing operation over the same network environment
