We present the results of performance tests to compare
two protocols for three-tier computing using the
Windows NT operating system. Three-tier computing
features a data server for stored databases (Tier I), an
application server that runs applications (Tier 2), and a
simple clientprogram that runs on desktop machines that
presents the user interface (Tier3).
Three protocols are available to communicate between
Tier 2 and 3: Intelligence Computer Architecture (ICA)
with and without data compression, and X Window. We
