“…With strong Wi-Fi/cellular connections, modern smartphones are capable of encoding, transmitting and decoding high-quality video in real-time [32]. Bieringa et al [7] evaluated the performance of Zoom, Microsoft Teams and Jitsi on computer-based videoconferencing systems by using experiments to understand the resource requirements of these tools. Significant differences in the resource usage of the different systems were found [7].…”

Significant differences in the resource usage of the different systems were found [7]. Results indicated that, on average, Zoom had the highest resource usage and performance variability compared to Teams and Jitsi.…”

During the COVID-19 pandemic and mandated global lockdowns, people and busi- nesses started the extensive use of video-conferencing applications for staying connected. This surge in demand and the usability of video-conferencing services has been severely overlooked in developing countries like South Africa, where one-third of adults rely on mo- bile devices to access the internet, and the per-gigabyte data cost is among the highest in Africa. Considering these numbers, we conduct a two-pronged study where 1) we measure data consumption of different Android apps through data measurement experiments and 2) we conduct interviews and usability assessments with bandwidth-constrained users to bet- ter understand the usability and Quality of Experience (QoE) of mobile video-conferencing apps. Usability is the degree to which specified users can use a product to achieve specified goals. In contrast, QoE measures the subjective perception of the quality of an application and the level of delight or annoyance with a service. The key benefit of this study will be to inform organisations that seek to be inclusive about these tools’ relative usability by letting them know about the factors influencing users’ QoE.

Since the global COVID-19 pandemic, a shift has occurred to remote education and work. This is enabled by various video conferencing systems like Zoom, Google Meet, Microsoft Teams which has consequently increased the pressure on digital infrastructure. Surprisingly, no prior research has been undertaken to understand the performance of various video conferencing systems.In this study, we aim to evaluate and compare the performance of video conferencing systems in the context of distributed systems. To achieve this objective, we designed experiments to compare the performance and scalability of Zoom, Microsoft Teams, and Jitsi. Furthermore, we designed and implemented an experimentation tool that automatically hosts and joins video conferences, and measures the network bandwidth, CPU usage, and memory usage.We observed that the video conferencing tools have a stable performance after the initial warmup time for up to 6 clients. Except for the high memory usage of Zoom web, which grows linearly in time until a certain upper bound. Hence, we do not recommend Zoom web for a small number of clients.
