perfkitbenchmarker/linux_benchmarks/kubernetes/agentic/k8s_chromium_density_benchmark.pyperfkitbenchmarker/linux_benchmarks/kubernetes/agentic/k8s_qps_benchmark.pyDescription: Adds two more GKE Agent Sandbox benchmarks:
Chromium Density: Measures browser interaction latency (navigate, evaluate, click, fill, screenshot) under concurrent Chromium sandbox sessions. Uses CDP (Chrome DevTools Protocol) from the orchestrator — no Node.js in the sandbox.
QPS Saturation: Measures scheduling throughput by firing sandbox claims at controlled QPS rates. Supports two modes:
agent(via orchestrator API) andraw_claim(direct SandboxClaim creation via kubectl). Identifies the QPS saturation point where warm pool drain causes TTFE spikes.
