An Empirical Study of eBPF Overheads in Ultra-Low-Latency Storage Stacks

Key Points

• The central aim is to evaluate the overheads of eBPF in ultra-low-latency storage systems.
• Evaluated verification and runtime costs of eBPF.
• Considered performance across near-DRAM devices and multi-tenant environments.
• Verification and runtime costs are generally small but can become significant in specific conditions.
• The findings confirm the feasibility of eBPF for programmable storage solutions.
