Has anyone benchmarked density under modern hardware-isolated runtimes?

Because security cannot be relaxed in the AI era, the historical tradeoff of isolation against utilization must be broken rather than chosen between; the talk names the mandate ("hard enforced boundaries, packed densely") without naming a mechanism. ## Key arguments (≤3) 1. **The workload profile is genuinely different**: high-volume, short-lived, unpredictable pod churn stresses the control plane in ways long-running services don't. 2. **The scarcity argument is the strongest part**: data centers cannot be built without limit — space, power, and capital are strictly capped — so resource efficiency becomes the only available lever. 3. **The paradox is well-formed but the solution is a slogan**: isolation historically costs utilization; security can't be relaxed; therefore the frontier must move rather than be optimized along — asserted with no technology, implementation, or measurement attached. ## Claim atoms ### Isolation has always cost utilization > [!quote] ID:rw_01kysr1p3gzq4kzrfnjddt4p1p > Historically, isolation always meant lower resource efficiency. If we isolate an environment to increase its security, to eliminate noisy neighbour, our resource utility will plummet **Where/why**: The stated core paradox, mid-talk. The tradeoff itself is real and well-stated; the claim that it can now be beaten is asserted without mechanism or measurement. Useful as a framing device, not as a finding. ## Permanent candidates - **Physical limits become the binding constraint once software efficiency is exhausted** — when demand for compute outruns what space, power, and capital allow to be built, efficiency stops being an optimization and becomes the only remaining lever. Strong candidate: independently corroborated by two other talks in this same conference batch (Fujitsu, NTT/SK Telecom), which strengthens it considerably. ## Processing checklist - [ ] Find whether current hardware-isolated runtimes (Kata, gVisor, Firecracker) have already narrowed the isolation/utilization tradeoff this talk treats as fixed - [x] Connect into the relevant MOC — [[3.
