The growing popularity of thin-client systems makes it important to determine the factors that govern the
performance of these thin-client architectures. To assess the viability of the
thin-client computing model, we measured the performance of six popular
thin-client platforms—Citrix MetaFrame, Microsoft Terminal Services, Sun Ray,
Tarantella, VNC, and X—running over a wide range of network access bandwidths.
We find that thin-client systems can perform well on web and multimedia
applications in LAN environments, but the efficiency of the thin-client
protocols varies widely. We analyze the differences in the various approaches
and explain the impact of the underlying remote display protocols on overall
performance. Our results quantify the impact of different approaches in display
encoding primitives, display update policies, and display caching and
compression techniques across a broad range of thin-client systems.
