Benchmarked February 2026 - AWS Graviton4

Sub-5ms authentication
at 1,000 concurrent sessions

FHE encryption, ZK proofs, biometric verification, and quantum signatures - all under load, all with zero errors. These numbers are our floor, not our ceiling. Benchmarked on AWS Graviton4. Production cloud hardware only goes up from here.

Concurrency Testing

Fast at any load. On a laptop.

AWS Graviton4 (c8g.metal-48xl, 96 cores). No cloud infrastructure, no GPU offloading, no distributed cluster. Production deployments on multi-core cloud instances scale linearly from here.

Benchmark Hardware
AWS Graviton4 (c8g.metal-48xl)
Single laptop. No cloud instances. No GPU acceleration. No distributed cluster. These are the numbers you get before any infrastructure investment.
Production Deployment
This is the floor, not the ceiling
Production cloud instances (96+ cores, dedicated memory) scale linearly. Horizontal scaling across nodes multiplies throughput with no architectural changes.
Operation Latency

Every operation, measured.

Median latency at 200 concurrent users on AWS Graviton4. Each operation runs over fully homomorphic encrypted data.

Under The Hood

Why it stays fast at scale.

Architecture decisions that make AWS Graviton4 outperform distributed FHE clusters.

POOL
Pre-warmed FHE Contexts
BFV and CKKS contexts with NTT tables built at startup, shared via zero-copy references. No per-request initialization cost.
LOCK-FREE
Atomic Concurrency
Lock-free data structures for rate limiting, usage tracking, and auth metering. Write contention eliminated from the hot path.
COALESCE
Compute Deduplication
Identical FHE operations within a time window are computed once and broadcast to all waiters. Turns O(N) into O(unique).
CACHE
ZK Circuit Caching
R1CS circuits and verification keys cached after first generation. Batch verification with parallel parsing for logarithmic-time proof checks.
ARC
Zero-Copy Keys
400KB+ FHE key sets shared via reference counting instead of deep copying. Nanosecond access under any concurrency level.
SIMD
Packed Ciphertexts
Biometric vectors packed into BFV slots for parallel encrypted computation. Up to 8x throughput on batch operations.
How We Compare

Different league.

H33 on a single laptop delivers the full post-quantum stack in less time than competitors take for a single operation on production infrastructure.

Capability H33 Nearest Competitor Advantage
Biometric Verification 220us (Turbo) Onfido - seconds ~1000x faster
FHE Encryption 150us Zama - 100x slower 100x faster

Hybrid Signature Overhead
The hybrid overhead is less than 1% of total auth pipeline time. You get backdoor insurance for free.
