“…Several studies [1,2,18] led by the same team have investigated the performance of virtual threads compared to Java platform threads and Kotlin coroutines. The findings indicate that virtual threads offer superior performance to both Java platform threads and Kotlin coroutines.…”

“…Moreover, these studies differ from ours in terms of service size. Specifically, the studies used: (i) an Ubuntu 18.04.3 64-bit virtual machine with a base memory of 9 GB running on Windows 10 64-bit OS with an x64-based processor with 16 GB of RAM [18]; (ii) an Ubuntu-20.04 64-bit machine with 13 GB of RAM, 8-core VM running on Windows 10 64-bit OS with an x64-based processor and 16 GB of RAM [2]; and (iii) an Ubuntu-20.04.3 LTS 64-bit machine with 16 GB memory and Intel® Core™ i7-6700 CPU @ 3.40GHz processor [1]. Notably, virtual threads were not compared to existing reactive programming models in these studies.…”

“…The Java language just introduced virtual threads 2 . This solution adds a layer of indirection between the threading model and the underlying non-blocking machinery to offer both a synchronous, imperative user API and better performance by leveraging nonblocking asynchronous primitives in the internals of the JVM.…”

Virtual threads are a highly anticipated feature in the Java world, aiming at improving resource efficiency in the JVM for I/O intensive operations while simplifying developer experience. This feature keeps the traditional thread abstraction and makes it compatible with most of the existing Java applications, allowing developers preferring synchronous imperative abstractions to benefit from better performance without switching to asynchronous and reactive programming models. However, limitations currently hinder the usability of virtual threads. These limitations must be considered when building a piece of software around virtual threads for they might have non-trivial effects. This paper (i) discusses the different strategies envisioned to leverage virtual threads in the Quarkus framework, (ii) gives an overview of the final implementation, (iii) presents the benchmark used to characterize the benefits of using virtual threads in a typical container environment where resources are scarce compared to using Quarkus with traditional thread pools and Quarkus with reactive libraries ; (iv) results are interpreted and discussed. Our study reveals that the integration of virtual threads in Quarkus doesn't perform as well as Quarkus-reactive. This seems to be due to a mismatch between the core hypothesis of Netty and virtual threads regarding the amount of threads available.
