Abstract: The recent shift in Generative AI (GenAI) applications from cloud-only
environments to end-user devices introduces new challenges in resource
management, system efficiency, and user experience. This paper presents
ConsumerBench, a comprehensive benchmarking framework designed to evaluate the
system efficiency and response time of GenAI models running on end-user
devices. Unlike existing benchmarks that assume exclusive model access on
dedicated GPUs, ConsumerBench simulates realistic multi-application scenarios
executing concurrently on constrained hardware. Furthermore, ConsumerBench
supports customizable workflows that simulate complex tasks requiring
coordination among multiple applications. ConsumerBench captures both
application-level metrics, including latency and Service Level Objective (SLO)
attainment, and system-level metrics like CPU/GPU utilization and memory
bandwidth. Through extensive experiments, ConsumerBench reveals inefficiencies
in resource sharing, unfair scheduling under greedy allocation, and performance
pitfalls of static model server configurations. The paper also provides
practical insights for model developers and system designers, highlighting the
benefits of custom kernels tailored to consumer-grade GPU architectures and the
value of implementing SLO-aware scheduling strategies.
