Resumo(s)
The Event Handler – a publish-subscribe broker
implemented over REST/HTTP(S) – is an auxiliary system of
the Arrowhead framework for IoT applications. During this
work we found that the existing implementation of the Event
Handler suffers from serious performance issues. This paper
describes the reengineering effort that ultimately enabled it to
reach much more acceptable levels of performance, by using
appropriate software configurations and design patterns.
Additionally, we also illustrate how this enhanced version of the
Event Handler can be modeled using Petri nets, to depict the
performance impact of different thread pool configurations and
CPU core availability. The main objective of this modeling
process is to enable the estimation of the system’s performance
to guarantee the required quality of service.
