Multikey 18.2.2 ((full)) ◆

MultiKey 18.2.2

is a specialized USB emulator driver primarily used to "back up" or simulate hardware dongles (like HASP, Hardlock, or Sentinel) used for software licensing. While 18.2.2 is an older release, it remains a common version in niche communities for enabling legacy software to run without physical hardware keys. Performance and Compatibility

• Throughput: Multikey 18.2.2 achieves 1.6–2.3× higher throughput than RocksDB transactional baseline on mixed workloads due to batched commits and lower write amplification.
• Latency: median write latency comparable; 95th percentile lower in heavy-concurrency writes due to nonblocking batched commits.
• Space: on-disk storage reduced by ~20% vs. baseline because of prefix compression and tombstone reclamation.
• Scalability: near-linear throughput increase to ~12 cores; contention causes increased aborts beyond 16 cores for large transactions, mitigated by adaptive batching.
