KEY BENCHMARK
0.4ms Enclave Dispatch
EXECUTIVE ABSTRACT
How we replaced 650ms Nitro VM boot penalties with deterministic pre-attested vsock worker rings written in zero-allocation Rust.
ARCHITECTURAL BENCHMARK & KERNEL ANALYSIS
Standard confidential compute tutorials spin up enclaves on demand, stalling P99 API latency past 600ms. By pre-booting attested enclave pools and multiplexing mTLS streams over lock-free virtio-vsock ring buffers, Bastion dispatches attested requests in 0.4ms.
CISO IMPLEMENTATION CHECKLIST
Pin enclave vCPUs to isolated NUMA nodes · Pre-verify PCR0/PCR8 measurements prior to BGP Anycast health promotion · Enforce zero heap allocations on hot packet paths.
