# Performance Benchmarks With GenesisDB 1.1.1 we've shipped a substantial performance upgrade for GenesisDB, focused on high-concurrency workloads. Write and read operations are now dramatically faster under heavy parallel load, with significantly reduced latency and far higher throughput, especially when many clients commit or stream events simultaneously. If you're building event sourced applications and need strong consistency without sacrificing speed, this update should make a noticeable difference. ### Benchmarks compared to a comparable event store:

Operation	GenesisDB	Competitor	Speed Advantage
Write 10,000 events to empty store (100 concurrent users)	7.9s	2m 18.5s	17.6× faster
Write 10,000 events to store with existing 10,000 events (100 concurrent users)	20.3s	2m 31.4s	7.5× faster
Read 20,000 events (1,000 requests, 10 concurrent users)	9.4s	1m 46.8s	11.3× faster
Read 20,000 events filtered by subject (1,000 requests, 10 concurrent users)	4.0s	52.8s	13.2× faster
Query 20,000 events by data field (1,000 requests, 10 concurrent users)	13.1s	2m 13.7s	10.2× faster

All performance benchmarks were executed using Grafana k6, simulating high-concurrency workloads with realistic request patterns. The tests included parallel writes, subject-scoped reads, full-stream reads, and query-filtered reads under controlled load profiles.
