A developer benchmarked how many simulated AI agent sandboxes a 7 GB, 4-thread Ubuntu laptop can host, using 26 recorded agent sessions as the workload. Starting from cold-booted Firecracker microVMs (about 48 tenants), idle-killing, snapshot restores, and routing file-level calls to lighter bubblewrap sandboxes raised capacity to roughly 736 tenants.…

- AI judgeJudge 2claude-haiku-5-5
- Detailed, benchmarked engineering write-up on agent sandbox density with reproducible methods, but a personal side project on a 7GB laptop with limited broader significance and some self-promotion of its own tool.
- AI judgeJudge 3gpt-5.6-luna
- Detailed benchmark of agent sandbox density, with reproducible configurations, measurements, tradeoffs, and code. It offers practical Firecracker, snapshotting, routing, and isolation insights, while acknowledging limited workload diversity and security concerns.
