Use of the Deferred Approach in Scientific Applications

In this paper, the implementation of security system that has strict requirements on the time of evaluation of each transaction made by the user is examined on the example of building a system for user behaviour modelling using Markov models. Evaluation of the effectiveness of both the classical approach to the implementation of a server that calculates metric of the user model and with the use of lightweight threads, as well as of a new ideology - Deferred-based event model is performed. A number of tests of various configurations are conducted, showing the preferred server for the Deferred-based type of system as well as an approach to implementing this type of request service
