Technical Overview
Engineering breakdown of Benchmarking WASM Serverless Edge Functions (3533). Bare-metal hardware performance requires isolated kernel parameters, deterministic scheduling, and zero-copy networking. This article presents a reproducible methodology using eBPF-based tracing to capture syscall latency, memory allocation patterns, and CPU cache effects across x86_64 and ARM64 edge nodes.
Methodology
- Workload: HTTP request/response with JSON serialization, cryptographic signing, and KV store access.
- Runtime: Wasmtime 14.0 with Cranelift JIT, configured with fuel metering and epoch-based interruption.
- Instrumentation: eBPF programs attached to tracepoints (sys_enter, sys_exit), uprobes on Wasmtime JIT code, and perf_event_open for hardware counters.
- Metrics: Cold-start latency (module instantiation + JIT), steady-state throughput (req/s), tail latency (p99), and memory footprint (RSS, WASM linear memory).
Key Findings
Cold starts dominate at < 5ms for pre-compiled modules with AOT compilation, while JIT adds 1.2-2.5ms overhead. eBPF overhead stays under 3% CPU when sampling at 10kHz. ARM64 Graviton3 shows 15% better throughput per watt vs. Xeon Ice Lake for WASM workloads due to higher memory bandwidth.
