This paper presents some experiments on Windows NT operating system trying to determine
its timing limits. Experiments were concentrated on the context switching abilities in a
multithreaded environment. For this purpose a program simulator is written and simulations
performed. We detailed some characteristic times for different process priority classes and
processor's speed. In this way we try to determine the usage of this operating system in a
time-constrained (real-time) environment. For comparison, simulations were also performed …

characteristic times for different process priority classes and processor's speed. In this way
we try to determine usage of this operating system in time-constrained (real-time)
environment. For comparison simulations were also performed on Windows 98 and Linux …
