Effect handler orient programming (EHOP) is a recently proposed programming paradigm that aims to provide a high-level abstraction in code. Using this paradigm, programmers are able to define operations as an effect, which are implemented by an effect handler. Functions can then use effects, allowing the effect operations to be used in this function. Depending on the effect handler that handles the effect, an effect can have different functionality. In this research, EHOP is compared to the traditional functional programming paradigm on readability, maintainability, modularity and performance for IO intensive applications. The comparison is carried out by two programming experiments that each apply one of the programming paradigms to create an HTTP server. The comparison of these programs show that EHOP improves the readability, maintainability and modularity but decreases the performance in response time and memory. The conclusion of this case study is therefore that EHOP affects IO intensive applications in a negative manner due to its performance overhead.
